$ php artisan list -V
Laravel Framework Lumen (8.2.1) (Laravel Components ^8.0)

Description:

When initializing vimeo/psalm package it complains that Illuminate\Foundation\Bus\Dispatchable Trait is missing. Hence it aborts.

This error has reported in the following places. https://github.com/Maatwebsite/Laravel-Excel/issues/2347 https://github.com/Maatwebsite/Laravel-Excel/issues/2221 https://github.com/spatie/laravel-webhook-server/issues/3

As someone has suggested, jobs can be dispatched without Dispatchable in Lumen. Errors vanish after removing the following lines from https://github.com/illuminate/queue/blob/master/CallQueuedClosure.php#L1-L16. Since I don't know the internals I'm reporting this as an issue instead of a PR

We usually don't account for tools like psalm. If you think something is broken here feel free to PR something. Thanks.

Thanks for the quick reply.

I doubt it has lead to break lumen apps. That's why the listed issues can be found on GitHub. I found this in my first ever Laravel/Lumen project. I'll try to open PR.
