Cannot deploy rowy to my firestore project. I constantly get this error:

Error deploying Rowy services: Cannot convert firestore.v1.Value with type unset.

in this step:

Let’s enable Rowy services for your project.

Tried deploying the project many times, deleting and creating account, creating new service accounts etc. Nothing helps.

Any idea what could be the issue? I also had dropped an email to support@rowy.io but didn't receive any reply.
