Lumen application doesn't show stacktrace while in debug mode

Question

I have two Lumen microservices with (as far as I can tell) identical configuration. One shows a user-friendly error page, one doesn't.

Both services have this simple controller method:

public function test()
{
    echo $a;
    exit;
}

One of the services only shows:

Oops! An Error Occurred The server returned a "500 Internal Server Error". Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

The other service shows the stacktrace, etc.

APP_DEBUG=true and APP_ENV=local on both environments. I verified these settings by echo'ing them in the controller method.

What setting could I be missing that prevents me from seeing the stacktrace?

do you see errors in logs? `storage/framework/logs/` I think its on this path. — devnull Ψ, Mar 21 '23 at 14:37
the problem must be in your php.ini which does not show error https://stackoverflow.com/questions/15949304/turn-off-display-errors-using-file-php-ini — devnull Ψ, Mar 21 '23 at 14:38
Both microservices are running on the same local server with the same php.ini, and in both cases the error ends up in `laravel.log` — Sherlock, Mar 21 '23 at 14:40
might be a cache issue... did you try `php artisan optimize:clear` ? — devnull Ψ, Mar 21 '23 at 14:42
Funny by the way, you found a question that I answered 10 years ago. — Sherlock, Mar 21 '23 at 14:43
`optimize:clear` doesn't exist in Lumen, but `cache:clear` does and doesn't resolve the issue. — Sherlock, Mar 21 '23 at 14:43

The problem was that I have a config/app.php file where the debug setting was missing. Adding 'debug' => env('APP_DEBUG', false), to the array solved my issue.
