"Publish" button fails since ~5:40 PM (March 10) — build succeeds but rollout fails

[xavi7x]

Since approximately 5:40 PM (UTC-3) today, the Publish button in Firebase

Studio consistently fails with:

Failed to publish app

Something went wrong creating your App Hosting rollout. Please try

re-publishing.

The last successful deployment was at 5:35 PM ("Implementada desde Firebase

Studio"). Every attempt after that fails at the rollout stage.

Running npm run build manually in the Studio terminal completes successfully —

Next.js 15.3.8 compiles, type-checks, and generates all 57 pages with no

errors. The issue is specifically with the App Hosting rollout triggered by

the Publish button.

firebase deploy from the terminal only deploys Firestore/Storage rules, not

the App Hosting backend, so it’s not a workaround.

Environment:

• Firebase Studio (cloud workspace)

• Firebase App Hosting

• Next.js 15.3.8 (App Router)

• Node.js 22

• Region: us-central1

What I’ve tried:

• Re-publishing multiple times — same error every time

• Verified npm run build succeeds locally in Studio terminal

• No changes to apphosting.yaml or project config between the successful 5:35

PM deploy and the failing attempts

I noticed UI changes in the Firebase console today, so there may have been an

infrastructure update that affected App Hosting rollouts.

Is anyone else experiencing Publish failures today?
