Web publish does not start — Firestore write channel returned 503; Publish button triggers no deploy

[petself]

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

I'm unable to publish my project to the web. The issue has persisted since yesterday, across full browser restarts.

When I click the Publish button in the "Test, Run & Publish" panel, no build or deploy starts. There is no progress indicator, no error dialog, and the "Last Deploy" timestamp does not update. No publish/deploy network request is fired when the button is clicked.

While debugging the network traffic I found that requests to the Firestore write channel (firestore.googleapis.com/.../Firestore/Write/channel, RID=rpc) were initially returning HTTP 503 (Service Unavailable), immediately followed by a terminate request. Read/Listen channel requests returned 200 normally. Later the same write channel requests started returning 200, but clicking Publish still does not start any deploy.

Project: Petself Express
Target domain: petself.flutterflow.app
Branch: main / Production

Expected Behavior

Clicking Publish should start a web build/deploy and publish the project to petself.flutterflow.app, updating the "Last Deploy" timestamp on success.

Steps to Reproduce

1. Open the project. 2) Open the "Test, Run & Publish" panel. 3) Make sure the target domain (petself.flutterflow.app) is selected. 4) Click the Publish button. 5) Observe that no build/deploy starts: no progress indicator, no error, "Last Deploy" timestamp does not change, and no publish/deploy network request is sent.

Reproducible from Blank

• The steps to reproduce above start from a blank project.

Visual documentation

Note: I will attach a screenshot/short video manually. For reference, the screen shows the "Test, Run & Publish" panel with the target domain petself.flutterflow.app selected and the "Last Deploy" timestamp unchanged after clicking Publish. When the Publish button is clicked, no build/deploy starts: there is no progress indicator and no error dialog. In the browser network tab, no publish/deploy request is sent on click; separately, the Firestore write channel (Firestore/Write/channel, RID=rpc) was returning HTTP 503 and later returned 200, but the publish still does not start.
