Hey all ... I'm getting an error saying 
prefect.exceptions.ClientError: [{'path': ['create_project'], 'message': 'Uniqueness violation.', 'extensions': {'code': 'INTERNAL_SERVER_ERROR'}}]
when I try to REcreate a project with the same name in 
backend cloud
.... Is this a known issue? Does anyone know of a workaround? (Details in thread)
To recreate it:
Copy code
prefect backend cloud
prefect create project foo
prefect delete project foo
prefect create project foo
...
Copy code
Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/prefect/client/client.py", line 1063, in create_project
    res = self.graphql(
  File "/usr/local/lib/python3.9/site-packages/prefect/client/client.py", line 473, in graphql
    raise ClientError(result["errors"])
prefect.exceptions.ClientError: [{'path': ['create_project'], 'message': 'Uniqueness violation.', 'extensions': {'code': 'INTERNAL_SERVER_ERROR'}}]

During handling of the above exception, another exception occurred:

Note: I tried through the UI as well. It does not work either, although it seems to pretend it did.

Projects are soft deletions so they are hidden from the UI because they take a while. They are marked for deletion and then eventually happen like 15 minutes later? It will work if you try it later. Deleting a project just has many steps. Could you mvoe the traceback to the thread when you get a chance?

Thanks. Ok, I'll try a little later. Can you clarify what you mean by "Could you mvoe the traceback to the thread" ... ?

The error, if you could move it to this chat thread to keep the main channel more clean

"Eventually happen" seems to have taken at least 3 hours. I guess I'll pause until tomorrow

Did that project have a lot of flows or flow runs? It’s dependent on how many deleted need to cascade

Chris Hatton

No. One of them had no runs at all.

Ok i’ll leave a note for the team to check why this may be taking so long

I can recreate the issue with a simple
Copy code
prefect create project foo
prefect delete project foo
prefect create project foo
Not trying to nag, I just wanted to let you that this did not resolve over night. I'd be happy to report an issue or a bug if you have a system or link to do so.

Ok I got no response but I suspect something in our deletion service is broken. I’m gonna escalate this. Thanks for letting me know!
@Chris Hatton our deletion service is currently off but if you DM me your tenant id and project we can delete it for you
It’s undergoing a refactor
