I’m trying to build a dockerfile, make an image and run it in a container; but i’m getting errors [closed]

This is the code I ran to try to build the container.

This is my terminal

docker build -t mynode-app:1.0 .

This is my server.js file.

This is the server.js file

const express = require('express');
const app = express();

app.get('/', (req,res)=>{
    res.send("welcome my boy to the app");
});

app.listen(3000, function (){
    console.log("app listening on port 3000");
});

This is the package.json file that has dependencies.

This the package.json file

{
    "name": "my-app",
    "version": "1.0",
    "dependencies": {
        "express": "4.18.2"
    }
}
