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

问题

This is driving me crazy second day. I'm new to Laravel and trying to get Laravel 6 work on Google App Engine Standard. Tried: This tutorial and other ones, but it still fails to load Laravel index page

What I have done:

Created new Laravel project
Checked that Laravel is working on local host with php artisan serve
Generated new key with php artisan key:generate --show
Created app.yaml file with:

runtime: php72

env_variables:
  APP_KEY: iktbUa2quYPV2av3zDx0XAuEVjwzVQY/oMfyI2PQNKk=
  APP_STORAGE: /tmp
  VIEW_COMPILED_PATH: /tmp
  SESSION_DRIVER: cookie

Modified bootstrap/app.php by adding $app->useStoragePath(env('APP_STORAGE', base_path() . '/storage'));
Rancomposer remove --dev beyondcode/laravel-dump-server
Also ran: php artisan cache:clear, php artisan route:cache, php artisan config:clear, php artisan view:clear (as other tutorials suggested)
And gcloud app deploy

And I get error: "Class 'Facade\Ignition\IgnitionServiceProvider' not found"

回答1:

I have experienced other errors as well, most of them gave me Error 500 and

nginx: [warn] the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /tmp/google-config/nginx.conf:3 in Stackdriver Logger

Also I was not aware that App Engine was executing composer.json on build (see Specifying Dependencies). And it seems the issue was that it cached that.

Everything was resolved by replacing command in step 7. :

gcloud app deploy with gcloud beta app deploy --no-cache

It seems that if I would have done all steps as in tutorial from the start I would not have any issues.
