i am trying to build a simple website, fetching data from github.
I have two datasets here.
The currentAPI is loaded correctly, while the other one throws error message “Uncaught (in promise) TypeError: album is not defined”, nevertheless the website loads the data!

    I have an async function:
    
            async function getData() {
            
            
              const previousPromise=fetch('https://raw.githubusercontent.com/balintov/matchmaker/refs/heads/main/previousPicturesAPI');
              const currentPromise=fetch('https://raw.githubusercontent.com/balintov/matchmaker/refs/heads/main/currentPicturesAPI');
              const responses = await Promise.all([previousPromise, currentPromise]);
              const dataPromises = responses.map(r => r.json());
              const [previous, current] = await Promise.all(dataPromises);
          for (var props in previous) {
            document.getElementById('main').innerHTML+= `<div class="previousTitle"><h2> Korábbi részek </h2><p>${previous[props].series} évad</p></div>`
            for (var episodes in previous[props]) {
              for (var episode in previous[props][episodes]) {
        
                //THIS CONSOLE MESSAGE RETRIVES THE DATA
                console.log(previous[props][episodes][episode].album.photolink);
        
                var episodeProp= previous[props][episodes][episode];
                document.getElementById('main').innerHTML+= `<div class="episode-container">
                <div class="episode-head">

/* HERE THE DATA WORKS, DOES NOT THROW MESSAGE */
                <h2>${episodeProp.episode_date}</h2>
                <p><a href=${episodeProp.episode} target="_blank">Hallgatom az epizódot!</a></p>
                </div>
                <div class="match-container">
                <div class="album-container">
                <div class="content-container">
                <h3>Album</h3>
    /* FROM HERE THROWS THE ERROR MESSAGE */
                <img src="${episodeProp.album.photolink}" alt="${episodeProp.album.description}" width="350" height="450" class="image">
                <p>${episodeProp.album.song}</p><p><a href="${episodeProp.album.spotifylink}" target="_blank">Hallgatom ▶️</a></p>
                </div>
                </div>
                <div class="picture-container">
                <div class="content-container">
                <h3>Kép</h3>
                <img src="${episodeProp.picture.photolink}" alt="${episodeProp.picture.description}" width="350" height="450" class="image">
                <p>${episodeProp.picture.description}</p>
                </div>
                </div>
                </div>
                </div>`
              }
            }
          }
        
        
        }
        
        getData();

I put the data set in JSON validator, I put the JS file into JS validator.
As I mentioned in the code comment, before the template literal string the data is not undefined.
Also in the template literal some data work perfectly.

The exact error message is: “Uncaught (in promise) TypeError: episodeProp.album is undefined”

I really do not understand what the problem is, could someone give a clue?

I have build an Sheets Add-on Which performs a task based on trigger setup by user
So the problem is that User sets triggers for multiple sheets e.g Sync

the trigger is executed but only for 1st trigger in the list of triggers not all

The PROBLEM IS only one trigger is being triggered for all of the setup triggers

Logs for one trigger & the same logs comes for all triggers

Active Trigger: -5962537404932988746 for function: fetchSynctriggerWithDetails
Active Trigger: -9139074510508922527 for function: fetchSynctriggerWithDetails
Active Trigger: -1495623190131824397 for function: fetchSynctriggerWithDetails
Active Trigger: -1224866675796805716 for function: fetchSynctriggerWithDetails
Active Trigger: 1983234386806141271 for function: fetchSynctriggerWithDetails
Active Trigger: -8082155554848723508 for function: fetchSynctriggerWithDetails

Response: {"success":true,"triggerDetails":{"trigger_id":"-5962537404932988746","sheet_name":"SKU","databaseid":"1","trigger_time":"1hour"}}

so the problem is it has all the triggers but it always run for

Response: {“success”:true,”triggerDetails”:{“trigger_id”:”-5962537404932988746″,”sheet_name”:”SKU”,”databaseid”:”1″,”trigger_time”:”1hour”}}

Because it can;t find
var triggerId = currentTrigger.getUniqueId();
for each trigger
& each time it returns -5962537404932988746 as current trigger ID

which is wrong

ANY HELP IS APPRECIATED

function createSyncTrigger() {

/// all the setup for setting up trigger 

// I am also saving trigger in PropertiesService

PropertiesService.getScriptProperties().setProperty(triggerId, JSON.stringify(triggerDetails));

}

Code snippet to fetch trigger details

function getTriggerDetailsSync() {
  var triggers = ScriptApp.getProjectTriggers();
   // Log all active triggers for debugging
  triggers.forEach(trigger => {
    Logger.log('Active Trigger: ' + trigger.getUniqueId() + ' for function: ' + trigger.getHandlerFunction());
  });

   //var currentTrigger = triggers.find(trigger => trigger.getHandlerFunction() === 'fetchSynctriggerWithDetails');

 // Get the current trigger that invoked this function
  var currentTrigger = ScriptApp.getProjectTriggers().find(trigger => 
    trigger.getHandlerFunction() === 'fetchSynctriggerWithDetails'
  );

  if (!currentTrigger) {
    Logger.log('No trigger found for fetchSynctriggerWithDetails');
    return null;
  }

  var triggerId = currentTrigger.getUniqueId();

}

I have this page which works well but
I want to add the content instead
I want to swap it

now
[ 1 ][ 2 ][ 3 ]
drag n drop
[ ][ 2 ][ 3+1 ]

but searching for this solution
drag n drop
[ 3 ][ 2 ][ 1 ]

When i run project in angular 17 it runs successfully. However when i made some changes in code and save changes then:

The browser page stucks in a reloading state

Also this error shown up:

Error during ngOnInit: ReferenceError: localStorage is not defined

Here is my ngOnInit code block:

async ngOnInit() {
    try {
      await this.fetchUsers();
  
      this.chatService.fetchMessages();
      this.chatService.messages.subscribe((messages) => {
        this.messages = messages;
      });
  
      const users = this.authService.getUsers();
      const { username, id } = this.authService.getUserNameFromToken() || {};
      this.name = username ?? '';
      console.log("Display token name:", this.name);
      let token = localStorage.getItem('authToken');
      console.log("Token: ",token);
      this.id = id ?? '';
    } catch (error) {
      console.error("Error during ngOnInit:", error);
    }

  }

I’m working on a React component that allows users to upload files. The files are managed in a state array where each file has additional metadata such as a unique id (required for DataGrid) and a docType field (e.g., INVOICE).

Here’s the state definition:

export interface EnrichedFile {
  id: string; // Unique ID for each file (required for DataGrid)
  docType: string; // A description of the file, e.g., INVOICE
  file: File; // The actual file object
}

const [selectedFiles, setSelectedFiles] = useState<EnrichedFile[]>([]);

Component Code:

Below is the relevant portion of my component where users can drag-and-drop or browse files to upload:

return (
  <Box component="div" className="w-96 overflow-hidden">
     .....
  </Box>
    {selectedFiles.length !== 0 && (
      <Animated className="w-full mt-4 h-48" animationIn="fadeInUp" animationOut="fadeOut" isVisible={true}>
        <ExDataGrid
          processRowUpdate={updateRowHandler}
          disableColumnMenu
          disableColumnFilter
          disableDensitySelector
          columnHeaderHeight={36}
          slots={{
            footer: () => (
              <div className="flex justify-center">
                <LoadingButton onClick={uploadHandler} variant="contained" color="primary" loading={isPending}>
                  Upload
                </LoadingButton>
              </div>
            ),
          }}
          columns={columnsDocumentsUpload(deleteFileUpload)}
          rows={selectedFiles}
        />
      </Animated>
    )}
  </Box>
);

Upload Process:

When I click the Upload button, I create a FormData object and attempt to append the files and metadata before sending it to the server via Axios. However, the FormData appears to be empty when inspected.

Here is my uploadHandler function:

const uploadHandler = useCallback(async () => {
  // Validate that all files have a docType
  const hasError = selectedFiles.some(file => file.docType.trim() === '');
  if (hasError) {
    return toast.error('Please select a document type for all files');
  }

  // Create FormData object
  const formData = new FormData();
  selectedFiles.forEach(file => {
    if (file.file instanceof File) {
      formData.append('files', file.file); // Append the actual file
      formData.append('metadata', JSON.stringify({ id: file.id, docType: file.docType })); // Include metadata for each file
    } else {
      console.error("Invalid file object:", file.file);
    }
  });

  // Debugging: Log FormData entries
  for (const [key, value] of formData.entries()) {
    console.log(`${key}:`, value);
  }

  mutate(formData);
}, [selectedFiles, mutate]);

Expected Behavior:

The FormData object should include the appended files (files) and metadata (id, docType) and send them to the server.

Questions:

1. Why is the FormData object empty even though selectedFiles contains valid File objects?
2. Am I appending files to FormData incorrectly?

I recently upgraded Node.js on my Windows machine to version v22.12, and now any script I run from a file exits immediately without displaying any output. For example:

> node test.js
# (no output, program finishes instantly)

Here is a minimal example of test.js (though the content seems irrelevant; even a single console.log() fails to produce output):

console.log("Hello from Node.js");
setInterval(() => {
  console.log("Still running...");
}, 2000);

Key observations:

1. If I run the same code inline using -e, it does work:

   node -e "console.log('Hello from inline'); setInterval(() => {console.log('Still running inline...');}, 3000)"
   

2. If I downgrade Node.js to v20.18, the file-based execution works as expected, producing output as normal.
3. Before upgrading to 22.12, everything worked correctly on the same machine.
4. After reverting to 20.18, it started working again without changing any other settings.

Question:

• Was there a change in Node.js v22.12 that affects how scripts should be started on Windows?
• Or could there be a specific configuration or security policy on my Windows PC that might cause this behavior?
• Has anyone else encountered this issue or found a workaround?

For now, I’m okay staying on v20.18 since it resolves the problem, but I’d prefer to upgrade if there’s a known fix or setting adjustment. Any insights would be much appreciated!

I want to see print something in console so I can see the values, its a live website that I dont have control, its not mine.

Here is what I did.

1. Went to SOURCES tab
2. opened that Javascript file
3. put console.log()
4. clicked CTRL+S
5. Then without re-freshing website, I clicked on that particular
   button on website, AJAX was sent, but no message in console

NOTE: that orange icone you see? it says “changes to this file were not saved to file system”

PS: I know I can see in XHR request payload but thats not I want, that is different data, I want see data at that specific point.

Is there any way to get OpenCV from repository? Which artifact should I add to pom.xml? Every tutorial I’d found is from ’14 and it seems like something changed – they say it is’nt in official Maven repository yet, but I’ve found entry:

when I’m using System.loadLibrary(Core.NATIVE_LIBRARY_NAME). Can I add this library in a way that would make my project include it and ‘forget’ about manually adding it to classpath?

I’m trying to create a layout in Next.js where the component rendered depends on the device (mobile or desktop). I want to prevent the desktop layout’s source code from being downloaded to the browser if the user is on a mobile device. Here’s what I have:

"use server";

import React, {ReactNode, ComponentType} from "react";

import {parseUserAgent} from "@repo/helpers";
import dynamic from "next/dynamic";
import {headers} from "next/headers";

interface Props {
  CommonWrapper?: ComponentType<{children: ReactNode}>;
  MobileComponent: () => Promise<{default: React.ComponentType<any>}>;
  DesktopComponent: () => Promise<{default: React.ComponentType<any>}>;
}

const withResponsiveLayout = async ({
  CommonWrapper,
  MobileComponent,
  DesktopComponent,
}: Props) => {
  const header = new Headers(headers());
  const parsedUserAgent = parseUserAgent(header);
  let isMobile = parsedUserAgent?.device.is("mobile");

  const Wrapper = CommonWrapper ?? React.Fragment;
  const Component = isMobile
    ? dynamic(MobileComponent)
    : dynamic(DesktopComponent);

  return (
    <Wrapper>
      <Component />
    </Wrapper>
  );
};

export default withResponsiveLayout;



// example

'use server'

async function Page() {
  const data = await getSomeData();

  return await withResponsiveLayout({
    CommonWrapper: ({children}: PropsWithChildren) => (
      <MandatoryAuthWrapper>
        <CommonProvier initialData={data}>{children}</CommonProvier>
      </MandatoryAuthWrapper>
    ),
    DesktopComponent: () => import("./Main"),
    MobileComponent: () => import("./MobMain"),
  });
}

I’m trying to render either a mobile or desktop layout based on the user-agent, and I want to ensure that the desktop layout never gets downloaded by the browser if the user is on a mobile device. I don’t want to make the layout responsive but rather load an entirely different layout based on the device.

Am I doing something wrong in my approach? How can I ensure the desktop component is excluded from the client-side bundle entirely when the user is on a mobile device?

In wkwebview，The web page image is not fully displayed, only part of it is rendered. Switch the app to the background and then to the foreground, and the incomplete image will be rendered correctly again.

enter image description here

The above is an example, the image already has height

The network is good, debugging in safri, you can preview the picture normally

I made a restaurant web application. I need to print the billing receipt in react web application using a network printer but when installing necessary libraries /packages it’s not getting installed and the same error is repeating on different libraries. Need to fix this code in front-end. When I print the code the receipt design is getting printed instead the HTML code is getting printed with the tags. And I’m designing it using tailwind css. The code is connected through IP address of the printer but when the print receipt button is clicked it prints the same HTML raw code which is given as text and not printing the receipt design.

I tried packages like node-thermal-printer, npm point-of-sale, npm escpos-network but none of them are installing and showing error as Unsupported engine node version. I tried changing the node versions but still it’s not getting installed. When the print receipt button is clicked it should not show the pop-up page which shows to select the printer type, print color, and etc., instead it should print the receipt directly. This should be done in webpage application.

When a user visits certain pages on a website, and they have the app installed, I’d like the app to open instead. I’m not entirely sure how to achieve this, but I assume it involves adding a meta tag or similar functionality to the pages.

For example, if the hosted website is https://example.com/ and a user visits https://example.com/stream, I’d like the XYZ application to open (if installed) and load the stream page within the app.

This functionality needs to be implemented in React Native. While I’m familiar with handling deep linking, this approach seems to require a different method.
