Cannot delete project due to Dialogflow V1 agent lien - old console inaccessible

Google Cloud Cloud Foundations & Onboarding
1

Hi everyone,

I’m trying to delete a Google Cloud project but I’m blocked by a lien from a deprecated Dialogflow V1 agent.

Project Details:

  • Project Name: Dialogflow-prebuild-agents
    • Project ID: (PII Removed by Staff)
      • Lien ID: liens/(PII Removed by Staff)-l3fd1a756-1b7f-438f-98c8-348ddb6caf60
    • The Problem:
    • When I try to delete or shut down the project in Firebase Console or Google Cloud Console, I get an error saying the project has an active lien that must be removed first. The lien was created by a Dialogflow agent.
  • What I’ve Tried:
    1. Deleting the lien via gcloud alpha resource-manager liens delete - Permission denied
      1. Accessing the old Dialogflow console (console.dialogflow.com) - The old console is no longer accessible
        1. Accessing dialogflow.cloud.google.com - Cannot find the agent there (it was a V1 agent)
          1. Dialogflow API calls to delete the agent - Permission denied
        3. The agent appears to be from the deprecated Dialogflow V1 (ES Standard Edition) which has been migrated/discontinued, but the lien remains on my project.
      3. Question:
      4. How can I remove this lien so I can delete my project? Is there a way to contact Google support to manually remove this lien, or is there another solution?
    3. Any help would be greatly appreciated!

Hey,

Hope you’re keeping well.

This type of lien is system-created and tied to a retired Dialogflow V1 resource, so it can’t be removed through the console or gcloud unless you have the resourcemanager.liens.delete permission at the organization or project level. Since the old Dialogflow V1 UI is gone and the agent is inaccessible, the only viable path is to have Google Cloud Support remove it manually. If you have a paid support plan, open a case in the Cloud Console under Support > Create case with the lien ID and project details. If you don’t have support, you can use the public support contact form and request escalation for lien removal due to a deprecated service. Make sure to include the exact lien ID and clarify that it’s blocking project deletion from a retired Dialogflow V1 agent.

Thanks and regards,
