I need help debugging this. So when I click the button on the first page to go to next page, it just refreshes the page. What could be wrong please? Here’s a recreation of the form. https://codesandbox.io/s/agitated-spence-q3vtqw
Tried passing the onSubmit as on onClick event. It takes me to the next page alright, but the data aren’t in the console.

I am geting the generatedCodeVerifier(), but how do you get the challengeFromVerifier(v) === returning as object[promise]. console.log(“code_verifier = + generateCodeVerifier()); var v = gernerateCodeVerifier(); console.log(“challenge = ” + generateCodeChallengeFromVerifier(v)); // object[promise]
Thanks @Moojjoo
I have the next problems with my code: my backend code doesn’t initiate when i try to compile it and make it send coordinates to my html page of a web server that i created in javascript on Visual Studio code.
First, i created a code with python to open the camera of my laptop and calculate the area of each square (or rectangles) that the camera could recognize. Then I created a web server with express and Socket.io. For this I created a directory on my computer to make this, and in a folder named public and another named nodejs_web_server.
Now, i will share the codes here. THE FIRST CODE IS:
import cv2
import numpy as np
import requests from socketIO_client import SocketIO, BaseNamespace
import json
IP_SERVER = 'localhost' # servers ip SERVER_URL = 'http://localhost:3000' # URL of Express server
print("Starting...") socketIO = SocketIO(IP_SERVER, 3000) try: socketIO = SocketIO(IP_SERVER, 3000) print("Connected to server") except Exception as e: print(f"Error by trying to connect to server: {e}")
cap = cv2.VideoCapture(0)
frame = cv2.imread('your_image.jpg') # Replace 'your_imagen.jpg' with the path of your image
while True: ret, frame = cap.read()
print(f"Readed frame: {ret}")
if not ret:
break
# Convert the image to a gray scale
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
# Apply a gaussian filter to reduce the noise
gray = cv2.GaussianBlur(gray, (5, 5), 0)
# detect the borders of the image
edges = cv2.Canny(gray, 50, 150)
# detect the contours of the image
contours, _ = cv2.findContours(edges, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)
# minimum area to recognize squares
minimum_area = 1000
for contour in contours:
perimeter = cv2.arcLength(contour, True)
approx = cv2.approxPolyDP(contour, 0.04 * perimeter, True)
if len(approx) == 4 and cv2.contourArea(contour) > minimum_area:
# Find the centre of the square
M = cv2.moments(contour)
if M["m00"] != 0:
cx = int(M["m10"] / M["m00"])
cy = int(M["m01"] / M["m00"])
coordenadas = {'x': cx, 'y': cy}
response = requests.post(f'{SERVER_URL}/coordenadas', json=coordenadas)
print(response.status_code, response.text)
# Send the values to server with the id "coordenadas"
coordenadas_json = json.dumps({'x': cx, 'y': cy})
socketIO.emit('coordenadas', coordenadas_json)
# invert the image horizontally
frame = cv2.flip(frame, 1)
# show the image in real time
cv2.imshow('Detection of squares', frame)
# stop the loop when 'q' is pressed
if cv2.waitKey(1) & 0xFF == ord('q'):
break
# wait 500ms
if cv2.waitKey(500) & 0xFF == ord('q'):
break
#close the camara and the window
cap.release() cv2.destroyAllWindows()`
Then i have this one named “app.js”:
var express = require('express');
var app = express();
var server = require('http').Server(app);
const io = require('socket.io')(server);
app.use(express.static('public'));
ArduinoSocketID = null;
io.on('connection', function(socket){
socket.on('coordenadas',(mensaje)=>{
console.log('mensaje del cliente', mensaje);
io.sockets.emit('coordenadas',mensaje);
//console.log(ArduinoSocketID);
});
});
server.listen(3000, function(){
console.log("Servidor corriendo en el puerto 3000")
});
Then this one “main.js”:
var socket = io.connect('http://localhost:3000', {'forceNew': true});
socket.on('coordenadas', (mensaje) => { console.log('coordenadas recibidas', mensaje);
var data = JSON.parse(mensaje);
console.log('COOR X:', data.x);
console.log('COOR Y:', data.y);
document.getElementById("19212438").innerHTML = "X=" + data.x + ", Y=" + data.y;
});`
Now, the number “19212438” its my ID in the list of my classmates that appears on my html page, in which one i want to trasmit the values of x and y in real time. (Each class members appears on my html code and each of them has its own ID. “19212438” its mine and i have to transmitt the x and y values generated on my backend code of python in the html page on real time).
Thanks for your support.
I have asked ChatGPT to solve it but it only generates even more and more errors during the compilation. I dont have experince in coding. Its my final project of my class in school. Hope someone could help me.

how can I override this Odoo class, I want to change the content of get date function, but I restart the service, the POS, even tried in private windows to avoid cache problems but Odoo is not seeing my custom js class :
odoo.define('pos_sale.SaleOrderRow', function (require) {
'use strict';
const PosComponent = require('point_of_sale.PosComponent');
const Registries = require('point_of_sale.Registries');

get date() {
return moment(this.order.date_order).format('YYYY-MM-DD hh:mm A');
}
get customer() {
const customer = this.order.partner_id;
return customer ? customer[1] : null;
}
get total() {
return this.env.pos.format_currency(this.order.amount_total);
}
/**

}
get amountUnpaidRepr() {

}
get state() {
let state_mapping = {

return salesman ? salesman[1] : null;
}
}
SaleOrderRow.template = 'SaleOrderRow';
Registries.Component.add(SaleOrderRow);
return SaleOrderRow;
});
I want to change the content of this function
get date() {
return moment(this.order.date_order).format('YYYY-MM-DD hh:mm A');
}
I tried :
odoo.define('slnee_appointment_sale.CustomSaleOrderRow', function (require) {
'use strict';
console.log('innnnnnnnnn XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX')
var SaleOrderRow = require('pos_sale.SaleOrderRow');
const Registries = require('point_of_sale.Registries');
const moment = require('moment'); // Import the moment library if it's not already imported
const CustomSaleOrderRow = SaleOrderRow => class extends SaleOrderRow {
// Override the date getter to return a custom date format
get date() {
// Get the order's date in UTC
const utcDate = moment.utc(this.order.date_order);
// Convert the UTC date to the browser's timezone
const browserTimezoneDate = utcDate.clone().local();
return browserTimezoneDate.format('YYYY-MM-DD hh:mm A');
}
};
Registries.Component.extend(SaleOrderRow, CustomSaleOrderRow);
return SaleOrderRow;
});
but it’s showing nothing in the web browser console, like it’s not even seeing my js file even it’s added in the manifest

How to create .aip file (Adobe Illustrator Plugin file)?
I know how to create .zxp file with ZXPSignCmd.exe.
But how to create .aip file?
I need something which will not be possible to open, so code inside will be protected, is .aip file good for that?
I have a javascript backend that I use to provide an API, which can be used to save and get strings from the blockchain.
I used truffle to deploy my contract on the Goerli test net.
And the contract is written in solidity as below:
contract StringStorage {
mapping(uint256 => string) public stringList;
uint256 public stringCount = 0 ;
function storeString(string memory _value) public {
stringCount++;
stringList[stringCount] = _value;
}
function getString(uint256 _index) public view returns (string memory) {
require(_index > 0 && _index <= stringCount, "Invalid index");
return stringList[_index];
}
function getCount() public view returns (uint256) {
return stringCount;
}
}
I created a script, that i used to test the deployed contract and I am able to save aswell as read strings from the blockchain. This is the script:
const Web3 = require('web3');
const contract = require('./BackendITProjektNODEJS/blockchain_setup/build/contracts/StringStorage.json');
const HDWalletProvider = require('./BackendITProjektNODEJS/blockchain_setup/node_modules/@truffle/hdwallet-provider');
const web3 = new Web3(new HDWalletProvider('myKey', 'https://rpc.ankr.com/eth_goerli')); // Replace with your Ethereum node URL
const contractAddress = 'myAdress'; // Use the address deployed by truffle migrate
const instance = new web3.eth.Contract(contract.abi, contractAddress);
async function storeString(stringToStore) {
const accounts = await web3.eth.getAccounts();
console.log(accounts)
await instance.methods.storeString(stringToStore).send({ from: accounts[0] }).then((receipt) => {
console.log('Transaction receipt:', receipt);
})
.catch((error) => {
console.error('Error:', error);
});
console.log(`String "${stringToStore}" stored on the blockchain.`);
}
async function getString(index) {
const storedString = await instance.methods.getString(index).call();
console.log(`Retrieved string at index ${index} from the blockchain: ${storedString}`);
}
// Example usage:
storeString("test123");
//storeString("String 2");
//console.log(getString(3)); // Retrieve the first string
//getString(2); // Retrieve the second string
This works perfectly fine.
Now I have similiar code in my backend and I am able to call the read function and read the strings I wrote with the above script.
But the StoreString function never gets executed successfully.
This is the code:
import StringStorage from '../blockchain_setup/build/contracts/StringStorage.json' assert { type: "json" };
import HDWalletProvider from '../blockchain_setup/node_modules/@truffle/hdwallet-provider/dist/index.js'
import {Web3} from "web3"
class BspChain {
constructor(){
this.contract = StringStorage
this.web3 = new Web3(new HDWalletProvider('myKey', 'https://rpc.ankr.com/eth_goerli'));
this.contractAddress = 'myAdress';
this.instance = new this.web3.eth.Contract(this.contract.abi, this.contractAddress);
}
async storeString(stringToStore) {
console.log(stringToStore)
const accounts = await this.web3.eth.getAccounts();
//await instance.methods.storeString(stringToStore).send({ from: accounts[0] });
await this.instance.methods.storeString(stringToStore).send({ from: accounts[0] })
.then((receipt) => {
console.log('Transaction receipt:', receipt);
})
.catch((error) => {
console.error('Error:', error);
});
}
async getString(index) {
//const storedString = await instance.methods.getString(index).call();
const storedString = await this.instance.methods.getString(index).call();
console.log(`Retrieved string at index ${index} from the blockchain: ${storedString}`);
return storedString
}
}
export { BspChain as default };
I am catching the following error:
Error: {
jsonrpc: '2.0',
id: 'e056ced5-bea4-4dc2-8663-2a57e5f0a967', //this naturally changes each try
error: { code: -32000, message: 'execution reverted' }
}
I am somewhat clueless.
Please notice I changed personal information.
I appreciate every hint and help I get.
Many Thanks in advance.

I have had a look for a memory leak but unable to find anything
The documentation examples are simple and clear so kudos for that but I have a simple question.
I would like to know how to structure data that is a bit more complicated than the greeting examples and I do not know how to move forward.
So for example, the app I am trying to create centers around 3 words:
sites contain switches, switches have ports and ports connect to each other across switches.
Switches each have a name(or number) and ports each have a number.
The user says thing like “On site 3 connect switch 5’s port 3 to switch 7 port 4”
The result is a data structure such as:
{
site:3
switches:[{number:5, port:3},{number:7, port:4}],
action:function(){
switches[0].connect(switches[1])
}
}
The data structure could be anything as long as it is consistent.
Question
I would like to know how to structure data that is a bit more complicated than the greeting examples and I do not know how to move forward.
The example below is an example of the kind of data I want to work with. I feel like all the numbers should be “variables” instead of hard coded and I don’t know how to convey that in NLP.js
manager.addDocument('en', 'switch 3 port 1', 'switch.create');
manager.addDocument('en', 'switch', 'switch.connect');
manager.addAnswer('en', 'switch.create', '{ switches:[{name:undefined,port:undefined}]}');
manager.addAnswer('en', 'switch.create', `{ switches:[{name:3,port:1}]}`);
manager.addAnswer('en', 'switch.connect', `{ switches:[{name:3,port:1}]}`);
I’m trying out the PDF loader for a langchain tutorial:
npm install langchain
npm install pdf-parse
import { PDFLoader } from "langchain/document_loaders/fs/pdf";
const loader = new PDFLoader("src/document_loaders/example_data/example.pdf");
const docs = await loader.load();
Regardless of what url I use for the PDF, I always get this error:
Uncaught TypeError: readFile is not a function
Could this mean that pdf-parse only works in node.js and not in the browser?
How can I load PDF files in the browser with langchain?

If I can slice this div into equal parts with pure js or a js library I think I can somehow get somewhere.
I did some research, but I couldn’t find this kind of div slice on the internet.
Is there anyone who knows about this thing and can help?
I use vue-advanced-chat component with vue 3
"vue-advanced-chat": "^2.0.7",
"vue": "^3.0.0",
I keep the entire object of the selected room roomSelected, which contains the canWriteMessage parameter, which defines for me whether the user can write and send a message or not.
<vue-advanced-chat
...
:show-footer="roomSelected.canWriteMessage"
...
/>
I have the entire vue advanced chat component located at the bottom of my website. The page is relatively long, contains article details, gallery, etc. and the chat is located below these data
PROBLEM:
when the client comes to the site, the page immediately tries to scroll through the entire content and come to the chat
respectively, the chat component tries to scroll the footer. when I set :show-footer="false", the client stayed up after being added to the page, which I consider correct
Expectation:
it shouldn’t be like that, the client should stay up and look at the detail of the article and gradually scroll down
I tried, but it didn’t help:
autoScroll: {
send: { new: false, newAfterScrollUp: false },
receive: { new: false, newAfterScrollUp: false }
},
I was wondering if it is possible to append text to a file (e.g. with writeStream) that is colored.
There was a lot of information about how to color console.log text, but I wasn’t able to find anything about colored text written into a file.
I’ve tried to use modules like colors or chalk and also adding nodejs color references (e.g. FgBlack = “x1b[30m”), but always with the fs.createWriteStream() and no result.
I have an SVG with some text in a foreignObject that I want to convert to an HTML image element <img src="data:image/svg+xml;utf8,%3Csvg%20xmlns..."> but resulting image looks a little bit different from the SVG. It looks like there is more line height in the resulting image. I’ve tried with text with different font families but the image and SVG still do not match.
Link to the code – https://jsfiddle.net/2x91gzjo/
JS:
const svgString = `<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="160"
height="143">
<foreignObject width="100%" height="100%"
style="line-height: normal; letter-spacing:0.25px; font-style:normal; font-weight:normal; color:#000000; font-size:11pt; text-decoration:none; text-align:left;font-kerning:auto;overflow-wrap:break-word;padding:10px;width:160px;height:143px;">
<style>
p {
margin-top: 0px;
margin-bottom: 0px;
}
</style>
<div xmlns="http://www.w3.org/1999/xhtml" style="">
<p><span style="font-family: Arial Narrow;">Hello World</span></p>
<p><span style="font-family: Arial Narrow;">Hello World</span></p>
<p><span style="font-family: Arial Narrow;">Hello World</span></p>
<p><span style="font-family: Arial Narrow;">Hello World</span></p>
<p><span style="font-family: Arial Narrow;">Hello World</span></p>
<p><span style="font-family: Arial Narrow;">Hello World</span></p>
</div>
</foreignObject>
</svg>`
document.getElementById('svg').innerHTML = svgString;
const data = 'data:image/svg+xml;utf8,' + encodeURIComponent(svgString);
const img = document.createElement('img');
img.src = data;
document.getElementById('svg').appendChild(img);
CSS:
svg p {
color: red;
}
svg, img {
position: absolute;
left: 10px
}
HTML:
<div id="svg"></div>
On the image below you can see that SVG (colored in red for convenience) has smaller line height than the generated image (colored in black).
It looks like this problem exists only in Chrome MacOS. If you open the jsfiddle link in Firefox the image and the SVG are aligned.
