Unable to delete project because of lien

Agent type tags: Dialogflow ES
Category tags: Project

Issue

When trying to delete a Google Cloud project, you get a notification that the project cannot be deleted because it has liens, and one of the liens is related to Dialogflow ES.

Solution

  1. Make sure that you no longer need the Dialogflow ES agent associated with the project. If you get a notification that the agent doesn't exist, this means that it has already been deleted.

    Dialogflow ES Console

    Open https://dialogflow.cloud.google.com/#/agent/project-id/intents.

    Note that this link differs from the link in the Google Cloud project deletion dialog.

    Dialogflow API

    Use the search method of the agent type.

  2. Get the lien name.

    gcloud

    Use the gcloud alpha resource-manager liens list command, as described in the Listing liens on a project documentation.

    API Explorer

    Use the Try this API panel on the Method: liens.list page:

    • Fill out the parent field, as suggested in the parameter description.
    • Click Execute.

  3. Delete the lien.

    gcloud

    Use the gcloud alpha resource-manager liens delete LIEN_NAME command, as described in the Removing liens from a project documentation.

    API Explorer

    Use the Try this API panel on the Method: liens.delete page:

    • Fill out the name field with the lien name that you got at step 2.
    • Click Execute.

  4. Shut down the project.

Console fails to set up project

Agent type tags: Dialogflow ES
Category tags: Console, Project

Issue

Received Failed to set up GCP project error when creating an agent with the console.

Solution

You may not have permission to create Google Cloud projects. Check if you can create a Google Cloud project directly from the Google Console. If you are not able to create a project, follow the recommendations provided in the error message.

Provide Complete Information to Support

When opening a support case with Cloud Support, include the relevant conversation IDs and logs collected during your investigation. This information is critical for debugging issues efficiently.
