Question

Answer 1

This is due to a missing permission. You need to check whether you have

firebase-storage@system.gserviceaccount.com

as a member with a "Storage Admin" role. If you don't have one, then add it. That would fix the issue.

Here's the step on how you can check and add permissions.

• Go to Cloud console
• Navigate to Storage
• Select your bucket then click show info panel.

You can also add the missing permission in the IAM & Admin if you want.
