I’m attempting to deploy a Laravel 8 app that uses a managed MySQL database to App Platform but seeing this error during deployment:

I’ve added the database to the app which set the DATABASE_URL environment variable and configured the trusted source. The app runs fine locally and can connect to this database without issue.

Any idea what I’ve missed?
