Project "xxx" has one or more liens on it to prevent accidental deletion. To delete the project, remove the liens first then try again

Question

I try to delete the GCP project, but got below information:

When I click the Remove lien link, the browser redirects me to Dialogflow web UI. But give me an error:

com.google.apps.framework.request.NotFoundException: No DesignTimeAgent found for project 'slate-bf0ec'.

I had deleted all Dialogflow agents before. I still can't delete the GCP project. There is nothing to delete on Dialogflow web UI.

Answer 1

A "lien" is a protection against deletion.

They can be added manually or automatically - e.g. adding a Dialogflow agent to a Google Cloud Platform (GCP) project automatically adds a lien to the project.

However, removing a Dialogflow agent does not automatically removed the lien - and the only way to get rid of it is by using the gcloud CLI.

Prerequisites

1. Setup the gcloud CLI (see https://cloud.google.com/sdk/docs/quickstarts)

2. Install the alpha component for gcloud

   gcloud components install alpha

   NB: Be aware that alpha commands can change without notice. See (https://cloud.google.com/sdk/gcloud/reference/alpha)

List existing liens on a GCP project

gcloud alpha resource-manager liens list --project [PROJECT_ID]

Delete existing liens

gcloud alpha resource-manager liens delete xxxxxxxxxxxxx-xxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Delete project

gcloud projects delete [PROJECT_ID]

Answer 2

I did it deleting the liens using the console.

1. Go to Google Cloud Shell & Set to your project.

gcloud config set project [PROJECT_ID]

2. List the project liens

gcloud alpha resource-manager liens list

3. Delete by name

gcloud alpha resource-manager liens delete [LIEN_NAME]

4. Delete the project

Answer 3

Try to create an agent [1] and specify slate-bf0ec as Google project then delete it using the Dialogflow console (the delete agent operation found in the General tab of its settings).
