-
Storage uploads/downloads not working

What I Need Help With
I need assistance diagnosing why my Firebase app cannot communicate with the backend services. Are there any debugging steps I should follow or common configuration issues I might have missed?
Thank you for your help!
There are a couple things I ran into that I can suggest checking.
-
In Firebase Console, can you see that the Storage bucket is empty and/or the Firestore collection is empty? Let’s assume yes, try grabbing the bucket name/collection name and re-prompting in Firebase Studio with specific instruction. Example from my app: “when the save button is clicked the values for wins, losses, and win % should write to new fields in the teams collection” - where teams was the name of the collection in my Firestore db.
-
Double check rules. I believe Gemini still has a challenge with deploying rules. When you say you checked the rules, were you looking at rules.json or the rules in the Console. Make sure these are the same (and allow write) in both places to ensure these are deployed.
-
The above items allowed me to resolve similar issues for write, though for delete actions, I needed to go further with prompting when Gemini was unable to resolve the failed delete and the errors were not obvious. When it seemed unable to support the delete action, I did an inspect on the preview to pull the error. See the attached image for details.
