How to troubleshoot Laravel failure to boot

I have a Laravel app that I recently overhauled and converted to an Laravel/Inertia/Vue 3 app. It works just fine on my local machine. I have pushed the code to a test server that uses the production environment. The first test gave me a 500 error that (in the apache error log) complained about an undefined customer user provider. The app has always used a customer user provider without a problem -- even so, I went ahead and created a brand new one just in case. but the error persists.

I then put a debug statement in the boot method of AuthServiceProvider. Nothing. So it appears (I say "appears" because I'm not certain what is going on here) that boot is not even executing, and the custom user provider complaint might have sent me in the wrong direction.

I've deleted all the caches multiple times, checked the code and logs for errors, and haven't come up with anything. Again, the exact same code works just fine on my local machine. The chief difference would have to be the .env file (and the OS; I use MacOS, and the server is running a version of Red Hat Enterprise), but I can't see anything in there (yet) that would cause this kind of an issue.

I've never encountered this with Laravel. How do you debug a Laravel app that won't even execute the boot method in the AuthServiceProvider? I'm sure that I must have done or overlooked something somewhere.

Any ideas or suggestions would be appreciated.

There are a few steps you can take to troubleshoot a Laravel app that fails to boot and doesn't execute the boot method in the AuthServiceProvider. Here are some suggestions:

Check the Laravel log files: Start by checking the Laravel log files for any error messages or exceptions. The log files are usually located in the storage/logs directory of your Laravel project. Look for any relevant error messages that could help identify the issue.
Enable debug mode: Set the APP_DEBUG variable in your .env file to true to enable debug mode. This will display detailed error messages on the screen, which can help identify the problem. Make sure to clear the cache after making this change.
Check the web server logs: Check the web server error logs (e.g., Apache error log) for any error messages related to your Laravel app. These logs might provide additional information about the issue.
Verify the environment configuration: Double-check the environment configuration on the test server. Ensure that the necessary environment variables are correctly set in the .env file. Pay attention to variables related to database connections, caching, and session drivers.
Clear caches: Clear all Laravel caches by running the following commands in your project's root directory:

php artisan cache:clear
php artisan config:clear
php artisan route:clear
php artisan view:clear

Check file permissions: Ensure that the necessary files and directories have the correct permissions. Laravel requires write access to certain directories, such as storage and bootstrap/cache. Make sure these directories are writable by the web server.
Verify PHP version and extensions: Check that the PHP version and required extensions match the Laravel version you are using. Laravel has specific PHP requirements, so make sure your server meets those requirements.
Test with a fresh Laravel installation: Create a fresh Laravel installation on the test server and see if it works. This will help determine if the issue is specific to your application or if it's a server configuration problem.

If none of these steps resolve the issue, it may be helpful to provide more specific details about the error messages or exceptions you are encountering.

so what do you see when you hit the home page route?

Does CLI work? eg php artisan route:list

have you correctly set the document root to the public folder?

Have you copied in an .htaccess file?

Thanks for responding. The problem kept morphing over the weekend as we attempted to troubleshoot. Error log messages changed a few times. At one point the custom user provider error was gone, only to be replaced by ext Illuminate\Contracts\Container\BindingResolutionException: Target class [translator] does not exist.

The key to getting it running was to remove Clockwork, which should not have been running on production anyway. We still don't really know what that class error was all about, or whether it has been completely resolved, but removing Clockwork at least stopped the error and allow the site to run. Sometimes you just don't know whether the error you are seeing is the actual cause, or a symptom of another problem.
