Firebase Hosting GitHub Action fails with "supplied version is the current active version" but changes are still deployed
21:42 25 Jun 2026

am using the FirebaseExtended/action-hosting-deploy@v0 GitHub Action to deploy a Flutter web application to Firebase Hosting. Every time I push changes to my code, the action runs and fails with an HTTP 400 error. However, despite the failure, the new changes are actually reflected on the live production site.

  • Project type: Flutter web application (build output is in build/web).

  • Action used: FirebaseExtended/action-hosting-deploy@v0.

  • Firebase project ID: hotel-delivery-65492.

  • Trigger: The workflow runs on push to the main branch.

  • Local behavior: If I run firebase deploy --only hosting locally, it works perfectly without any errors.

  • Additional warning (non-fatal): My firebase.json contains a property "flutter" which triggers a warning (unknown property), but removing it does not fix the issue.

Request to https://firebasehosting.googleapis.com/v1beta1/projects/-/sites/app-teste-65492/channels/live/releases?versionName=projects%2F43565238095%2Fsites%2Fapp-teste-65492%2Fversions%2Fffg60o2a0014032323 had HTTP Error: 400, Can't release to `projects/-/sites/app-teste-65492/channels/live`: supplied version `projects/43065038795/sites/app-teste-65492/versions/ffg632a044032123` is the current active version.
