GCP Firestore API is not available for Cloud Datastore projects

Question

I was trying to use the GCP filestore, following the simple quick example in the product website and get an error: "google.api_core.exceptions.FailedPrecondition: 400 The Cloud Firestore API is not available for Cloud Datastore projects."

I did use the datastore before in the same project, I then disabled the datastore api in the project and try out the example, still get the same error any one can suggest what to do other than creating a new project ?

Answer 1

If you have an empty Cloud Datastore database and you never executed a write to the database, you can upgrade to Cloud Firestore in Datastore mode or Native mode, by clicking the ‘’UPGRADE TO FIRESTORE’ button on the ‘Datastore/Entities’ page.

If you do not receive the option, then your database instance will be automatically upgraded at a future date(link). If you upgrade from Cloud Datastore to Cloud Firestore in Datastore mode or from Datastore mode to Native mode, you cannot undo the operation.

Here is the link to the Doc: https://cloud.google.com/datastore/docs/upgrade-to-firestore

Answer 2

I had The Cloud Firestore API is not available for Datastore Mode projects with an empty Firestore.

I've solved the error with the steps:

1. Open Firestore in your web browser.
2. Create at least one collection.

Sadly, Google error messages are useless, as you see by this example.
