Error 500 on a working docker container

Question

I'm using a slimframwork 3 app on laradock (nginx, mariadb, phpfpm, php 5.6) so I made a stupid syntax error:

$view->addExtension(new \Slim\Views\TwigExtension(
$container->router,
$container->request->getUri(),
));

the comma after the getUri() was giving me error 500 on chrome and that was frustration so I tried my app on wamp on windows and I get:

Parse error: syntax error, unexpected ')' in C:\wamp64\www\app\bootstrap\app.php on line 21

why was I having a 500 error with no clue of what was wrong.

P.S. I've set displayErrorDetails to true

Shoutout to Phil who solved this issue.

So when you use laradock and you come to a situation like this and you want more specific details about the error, you can either check your php-fpm container logs with:

docker logs -f <your container>

or set the "display_errors=On" on laradock/php-fpm/laravel.ini and you'll see your error message on your browser instead of error 500.
