How to change /workspaces root folder as it is breaking deployment?

Hey guys,

I have a Laravel app which is working fine locally but when deploying to App Platform via Github I keep getting this error:

The line being referenced here is $app = require_once __DIR__.'/bootstrap/app.php';

I’ve tried changing the source_dir to ./, but it didn’t resolve the issue. The deployment log indicates that the workspace root is set to /workspace, which may be causing the problem:

1 01:09:52] │  ✔ cloned repo to /workspace
[2024-03-11 01:09:52] ╰────────────────────────────────────────╼
[2024-03-11 01:09:52] 
[2024-03-11 01:09:52]  › applying source directory ./
[2024-03-11 01:09:52]  ✔ using workspace root /workspace

My Laravel app includes a built-in installer that resides at a sub-URL. Locally, when I run php artisan serve and access the direct URL, it’s also broken until I navigate to the /install subdomain.

I’d greatly appreciate any advice or insight on how to resolve this deployment issue. Thank you!
