Is there a new API requirement for deploying Cloud Functions that wasn’t there before?

Error waiting for Creating CloudFunctions Function: Error code 7, message: Build failed: Cloud Build API has not been used in project 669636788185 before or it is disabled. Enable it by visiting <https://console.developers.google.com/apis/api/cloudbuild.googleapis.com/overview?project=669636788185> then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry.

I'm not aware of any changes related to this. Is your IamPolicy or IamBinding referring to Cloud Build perhaps?

Nothing changed on our end and all of a sudden our CI pipelines started failing
