After running composer update in my Laravel 9 project, I encountered the following error message:

Writing lock file

Generating optimized autoload files

In Finder.php line 588:

  syntax error, unexpected token ")"


Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1

It seems the update completed, but something went wrong and now in the console I get a syntax error, unexpected tag ")" Error on Finder.php: 588.

I checked the file and it looks correct.

When I open the project in the browser, I get this error:

Fatal error: Uncaught RuntimeException: A facade root has not been set. in /var/www/html/vendor/laravel/framework/src/Illuminate/Support/Facades/Facade.php:334

I also cleared bootstrap/cahce/ and storage/framework/cache/data/, storage/framework/sessions/, storage All caches in the /framework/views/ folder.

I am using PHP version 8.0.16.

Composer version 2.0.12 2021-04-01 10:14:59.

Any idea how to solve this problem?
