Laravel-medialibrary: php artisan package:discover error

[philippkreis]

Hi,

working fine in my local dev env, I am facing problems with V8 when trying to deploy to Ubuntu servers. I tried to remove the generated config but the effect is the same...

`> @php artisan package:discover --ansi

Symfony\Component\Debug\Exception\FatalThrowableError : Class name must be a valid object or a string

at /home/forge/atl.bfd.space/vendor/spatie/laravel-medialibrary/src/MediaLibraryServiceProvider.php:23
19| $this->registerPublishables();
20|
21| $mediaClass = config('media-library.media_model');
22|

23| $mediaClass::observe(new MediaObserver());
24|
25| $this->loadViewsFrom(__DIR__.'/../resources/views', 'media-library');
26| }
27|

Exception trace:

1 Spatie\MediaLibrary\MediaLibraryServiceProvider::boot()
/home/forge/atl.bfd.space/vendor/laravel/framework/src/Illuminate/Container/BoundMethod.php:32

2 call_user_func_array()

Please use the argument -v to see more details.
Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1`

Any idea how to face this?

Many thanks,
Philipp

Have you cleared all caches? Including the config cache?

[philippkreis]

Hi, I tried to but all clearing commands are failing with the mentioned error :-(

[phkreis]

Ok found the problem on my end: When installing the Media Lib 8 package I was on PHP 7.3 on this server. The update was done later. This lead to the problem that I manually had to uninstall the ML first, then reinstall. Now working out fine.

Thanks for your support, it was my fault ;-)

I have the same problem. Both local and server are running on 7.4. Works local and in github actions but gives this error on the server.

I tried removing my vendor folder on the server and doing a composer install again like @phkreis , but same problem.

[Christophvh]

Found it. It is not possible to triggerphp artisan config:clearsince the autoloading fails, but it is possible to delete bootstrap/cache/config.php . If I delete that file it works!

[mohanad69]

steps are:
php artisan config:clear
php artisan cache:clear
remove vendor folder and composer.lock
composer install and try again

[bsam2019]

If you are getting the error in deployment, delete the config in the cache, do the following;

sudo rm (YOU PROJECT PATH HERE)/bootstrap/cache/config.php

on ubuntu server
