Problems while creating a datalab in GCP

I'm getting a strange error while trying to create a datalab in GCP. gcloud is up to date, all necessary APIs are enabled. I'm following these instructions https://cloud.google.com/datalab/docs/quickstart

Any ideas on what went wrong here?

This error looks like you've deleted in some wayCompute Engine default service account. Please go to IAM & Admin -> Service Accounts and check if you still have service account with name Compute Engine default service account.

To solve this issue follow instructions Undeleting a service account:

In some cases, you can use the undelete command to undelete a deleted service account. You can usually undelete a deleted service account if it meets these criteria:

• The service account was deleted less than 30 days ago.

  After 30 days, Cloud IAM permanently removes the service account. Google Cloud cannot recover the service account after it is permanently removed, even if you file a support request.

Also, you can try to reach Google Cloud Support for further instructions.
