CHECK NEW MESSAGE FOR UPDATED ERROR

~~Just like the best coding things--I have no idea what's happening here.~~

My code has worked in the past with previous releases of my app and now it just doesn't. I really don't know.
Basically, when starting my electron app in VS Code, everything works perfectly but when I build it with electron-forge and run the setup.exe the app starts but the button I have that normally calls a child process just doesn't seem to be working.

I don't know exactly what code I would post so here's my Github: https://github.com/spjoes/WardenMC
The button is in play.html that should call "loadGame()" which should send the "startGame" message using ipcRenderer.send to main.js to run the game by starting the childProcess "run_account.js" in the WardenNew folder

My setup:
Windows 11 (tested on Windows 10 as well)
Updated to Electron v22 (was on 19*)
Updated to Electron-Forge 6.0.4 (was on 6-beta*)

* means that my code was on that version for previous releases and it worked then but on this release it started not working so I tried updating. Hopefully that makes sense

Thanks in advance!

Since posting, All ive discovered is that right when I fork the childprocess it immediately exists with error code 1 and signal of "null".

I tried doing a childProcess.stdout.on('data') but thats not outputting anything since it immediately exits as I explained above

Electron childProcess crashes immediately only after built with electron-forge

Im going to make a new message with all the new info:

Hi! Basically, everything works perfectly when running my electron app through the terminal in vscode while developing. Right when I pack it into an .exe with electron-forge though, the app no longer works as intended. In my app, when clicking "PLAY", it normally starts a childprocess using childprocess.fork in main.js. Except, after being built the childprocess crashes immediately with code 1 and signal null when clicking the "PLAY" button

My setup:
Windows 11 (tested on Windows 10 as well)
Updated to Electron v22 (was on 19*)
Updated to Electron-Forge 6.0.4 (was on 6-beta*)

* means that my code was on that version for previous releases and it worked then but on this release it started not working so I tried updating. Hopefully that makes sense

Use absolute path to js file for fork

#

If problem with file thats run in fork

#

Or your fork script have errors

snow fable Dec 26, 2022, 6:02 PM

#

The forked script doesnt have errors. If it did, it wouldnt even run in "dev" mode

snow fable Dec 26, 2022, 6:03 PM

#

stiff rampart Use absolute path to js file for fork

How would this help? When printing out the file path its using in an external .txt file it shows a file that im trying to fork does exist so its not an issue of it not being able to find the file

stiff rampart Dec 26, 2022, 6:24 PM

#

If it run in dev in doesn't mean it 100% run in prod build

snow fable Dec 26, 2022, 6:39 PM

#

stiff rampart If it run in dev in doesn't mean it 100% run in prod build

I know but the same file is being run and im certain the file is present because I verified

stiff rampart Dec 26, 2022, 7:06 PM

#

run your prod app from cmd

#

childProcess.stdout.on('data') for normal data

#

stderr for errors

snow fable Dec 26, 2022, 7:10 PM

#

stiff rampart `childProcess.stdout.on('data')` for normal data

I tried this. The issue with it was it crashes instantly and nothing gets output from that

stiff rampart Dec 26, 2022, 7:24 PM

#

does blank js file work with fork after build?

#

with console.log output in it

#

#

looks like it work

#

if it exit then it have error in it

snow fable Dec 26, 2022, 8:27 PM

#

stiff rampart if it exit then it have error in it

But why would it error in prod and not dev?

stiff rampart Dec 26, 2022, 8:28 PM

#

for many reasons

snow fable Dec 26, 2022, 8:29 PM

#

How would I even go on about debugging something like this?

stiff rampart Dec 26, 2022, 8:29 PM

#

add console.log for debug output into console

#

run app from command line

#

add logging system

snow fable Dec 26, 2022, 8:33 PM

#

stiff rampart run app from command line

Assuming you mean doing start filename.exe from cmd, that doesnt do much as it doesnt output anything in cmd, it just runs the app

stiff rampart Dec 26, 2022, 8:33 PM

#

just filename.exe

snow fable Dec 26, 2022, 8:34 PM

#

same issue, no output in cmd

stiff rampart Dec 26, 2022, 8:34 PM

#

then problem unsolvable

#

i am not able to help you because i am not able to run it

snow fable Dec 26, 2022, 8:40 PM

#

Wait. I think I solved it.

#

I may be the const { app } = require('electron'); line

#

idk why, but it wasnt needed anyways

#

im gonna build the app
