Firestore database inaccessible — App Engine SYSTEM_DISABLED, cannot unlink or re-enable

Google Cloud Database
1

Hi everyone,

I’m stuck in a situation where my Firestore default database in project is completely inaccessible and I’ve run out of options to fix it.

The problem: The Firestore database has appEngineIntegrationMode: ENABLED, and the linked App Engine app has servingStatus: SYSTEM_DISABLED. This causes the error:

“The database (default) is disabled for project XXX. The database has an App Engine app and this app is disabled.”

What I’ve tried:

  1. gcloud app update to re-enable App Engine → fails with internal error (Error Response: [13] An internal error occurred while calling SICP)

  2. REST API PATCH to disable appEngineIntegrationMode via https://firestore.googleapis.com/v1/projects/(PII Removed by Staff)/(default) → returns 404

  3. gcloud firestore databases update (alpha + beta, SDK 562.0.0) → --app-engine-integration-mode flag does not exist

  4. App Engine settings page in Cloud Console → returns 404

The App Engine app exists (gcloud app describe returns valid output) but is stuck in SYSTEM_DISABLED state, and any attempt to update it hits a backend error. The Firestore database is therefore permanently unreachable.

I don’t have a support plan to file a technical support ticket. Has anyone encountered this before or know a way out? Is there any Google employee who could help escalate this?

SDK version: 562.0.0

Thanks in advance!
