Laravel with App Engine Standard Class 'Facade\Ignition\IgnitionServiceProvider' not found [SOLVED]

composer remove --dev facade/ignition helped in my case  

ErrorException (E_NOTICE) Undefined index: name laravel 7

I think I had the exact same error the other day, and for me, the solution was to downgrade the composer with:

composer self-update --1

#laravel #error
