SDM enableGoogleCloudPubSub returns 404 - Soft-gated project?

I’m trying to enable Pub/Sub event streaming for my SDM enterprise but the enableGoogleCloudPubSub API endpoint returns 404.

Details:

  • Enterprise ID: (PII Removed by Staff)
  • Project: (PII Removed by Staff)
  • Topic: projects/[PII Removed by Staff] (exists)
  • Endpoint: POST /enterprises/{enterprise_id}:enableGoogleCloudPubSub
  • Error: 404 Not Found

What I’ve verified:

  • Device is event-capable (has CameraMotion and CameraPerson traits)
  • Pub/Sub topic exists in GCP
  • Other SDM endpoints work (GET /enterprises/{enterprise_id}/devices returns 200 OK)

Question:
This appears to be a “soft-gating” issue. Has anyone experienced this and found a solution? Or can a Google engineer help enable this feature?

Thank you for any assistance!
