I had problems deploying a recent commit that I would appreciate some insight on.

Here is the log :

Jan 20 10:43:24 PM  ==> Build failed 😞

From what I gather, the line causing the error is in my index.js :

import KeyboardController  from "./Controller/keyboardcontroller.js";

This build occurs without error on my local machine so its something I must’ve fumbled with my webpack.config.js?

I have multiple imports before the line that causes the error but they do not cause errors.

I can provide more information if needed

Hi there

It might up upper/lowercasing problem. In linux filepaths are case-sensitive. Maybe the Controller folder is controller or keyboardcontroller.is should be KeyboardController.js

Michael_Douglas · January 21, 2023, 9:43pm

Sorry for the screenshot but this is just a sanity test to make sure Im not making a dumb error somewhere.

My cases appear to be correct?

I will say that the file keyboardcontroller.js was KeyboardController.js but I changed it to stay consistent with my file formatting.

Michael_Douglas · January 21, 2023, 10:20pm

So after changing redoing the import for keyboard controller, VSCode auto imported it as import KeyboardController from './Controller/KeyboardController'; Which confuses me endlessly.

Now the error for the keyboard controller has gone away, the new error is with the import right after it, the JoystickController.

Anyone has an explanation on how this could happen?

al_ps · January 23, 2023, 1:45pm

Hi,

It sounds like you’re describing casing issues. Linux (as used by Render) has a case-sensitive filename. The code and filesystem need to match. If you import ./Controller/KeyboardController, the file folder needs a capital C and the filename a capital K & C.

Michael_Douglas · January 23, 2023, 5:40pm

Thank you for the response,

I double checked the cases, and you can see from the screenshot I sent that they appear to be correct. The thing that VSCode auto imports is technically correct because it works, but! The directory and file names do not match what the import details, hence my confusion.

al_ps · January 23, 2023, 7:54pm

It’ll may be more about what Git has stored, changes in file casing don’t always get picked up. Maybe check the file casing in GitHub.

Michael_Douglas · January 23, 2023, 9:55pm

This was the problem. Im not sure how it happened, but there was inconsistent naming with the keyboardcontroller.js. Even though I was pushing changes to this file into the repo, my Git repo had the file named KeyboardController.js while locally on my machine it was being identified as keyboardcontroller.js

Thank you
