I have an old project (~1.5 years) that I want to start working on again. It shows up in the project list in the developers console. I am wanting to add an App Engine component to the project, but this item is missing from the categories on the left, i.e. under Compute I only have "Compute Engine, Container Engine, Click to Deploy".
Another project that I started more recently also lists "App Engine" before "Compute Engine".
I am thinking that this is an older project that hasn't been updated completely on the back-end. When I recently (this week) went into the project, a popup asked me to accept a Project ID(i.e. random-word-####). Previously the project didn't have a Project ID, just a Project Number.
I tried to follow a process that I saw for linking an App Engine to an existing Cloud Project, but creating a new App Engine project automatically creates a new Cloud Project.
Is there a way to be able to create a new App Engine program under an older Cloud Project?
Adding App Engine support to existing projects that were created outside of Developers Console is currently not possible. This is something we are working on, and I expect it to be added in the coming months.
