I have already created a DB instance in GCP Playground. But when I want to access them using Cloud shell to create DB and tables, there is an error like this:
ERROR: (gcloud.sql.connect) PERMISSION_DENIED: Cloud SQL Admin API has not been used in project clgcporg8-016 before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/sqladmin.googleapis.com/overview?project=clgcporg8-016 then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry. This command is authenticated as [email protected] which is the active account specified by the [core/account] property.
How to solve the error?
