Generating optimized autoload files [[email protected]]: Class Illuminate\Foundation\ComposerScripts is not autoloadable, can not call post-autoload-dump script

Hi @nickfan,
i'm running on a problem when deploying my laravel project remotely to the server.

When it tries to run "composer dump-autoload --optimize" or any "php artisan..." I get the error

Generating optimized autoload files
Class Illuminate\Foundation\ComposerScripts is not autoloadable, can not call post-autoload-dump script
> @php artisan package:discover --ansi
PHP Fatal error:  Uncaught Error: Class 'Illuminate\Foundation\Application' not found in /var/www/crechedigital.com/pre-prod/releases/release_20200403135242/bootstrap/app.php:14

Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 255

If I execute a "composer update" before on the server, it works. But I dont think it is the recommended approach. Have you already faced this or know how can I resolve?
Thanks in advance, cheers from Brazil.

have you ever tried to update your global composer component by:

composer global update

or try to

composer install

not composer update
