Firebase Storage creates a default BUCKET in the Google APP Engine free tier. This allows you to QUICKLY get up and RUNNING with Firebase and Firebase Storage, without having to put in a credit card or enable a billing account. It also allows you to easily share data between Firebase and a Google Cloud Platform project.

There are, however, two known cases where this bucket cannot be created and you will be unable to use Firebase Storage:

A project imported from Google Cloud Platform which had a Google App Engine Master/Slave Datastore application.

A project imported from Google Cloud Platform which has domain PREFIXED projects. For example: domain.com:project-1234.

There are currently no workarounds to these issues, and we recommend that you create a new project in the Firebase console and enable Firebase Storage in that project.
