Heroku gets wrong filepath for index.js-CodePudding

I tried to start my discord bot via heroku and it didn't start, when i checked the logs it gave me this response

Starting...
internal/modules/cjs/loader.js:905
throw err;

Error: Cannot find module 'Discord.js'

To me it seems like it tries to start the index.js file through the filepath /app/index.js but the file is not located in /app/index.js but instead just /index.js and I never even entered anything about the /app filepath anywhere so I dont know why it does this

Edit: I realised that the logs didnt show anything useful ton search because I entered the logs too late and if I entered them earlier I would see more info about the error. Heres what it said earlier

The issue is probably located in the package.json file because there is a field called main there which defines where your main file is located.

{
    "name": "lhubot",
    "version": "2.2.6",
    "description": "",
    "main": "index.js",
    ...
}

I found a answer myself, i wrote the wrong name for discord.js in require('discord.js'). I wrote "Discord.js" instead of "discord.js". Not sure why heroku found it as a problem but it was fine when i ran it on my own computer but that was the solution for me.
