Account not found for tombstone account (Creating a notebook instance)

Question

I'm trying to setup my GCP account, so that I can use a cloud GPU to run my Tensorflow projects.

I am following this guide from google, but for some reason, when try to create a new notebook instance, I get the following error:

Account not found for tombstone account.

I have absolutely no idea what a tombstone account is, and how I would create one. Google doesn't mention anything about this, nor in the guide, so I really hope someone could point me in the right direction here.

Answer 1

"Account not found for tombstone account." is seen normally when you delete a Service Account and try to use it or recreated it after a short period of time. I would try to create a new Service Account with a different name and specify it when you create the new AI Platform Notebooks instance.
