When deploying my application to google app engine

Answer 1

The DuskServiceProvider is usually only registered when composer dev dependencies are installed, it appears that when you are deploying to Google App Engine it is not installing any of your composer dev dependencies.

You'll either a) want to make sure that you are not registering the DuskServiceProvider manually anywhere in your code, b) running any tests which rely on the the Dusk package, or c) ensure your deployment script is also installing the dev dependencies.
