Prefect Community

Getting a bizarre error when creating a project with the CLI.

The referenced project (`veg_management`) was recently deleted with `prefect delete project veg_management` because I had some old flows in there I wanted to clean-up. But now when I attempt to recreate it I get the errors below. Note that if I change the name of the project (e.g. `veg_management_`) then it works.

Hey <@U034LCGR4EB>, could we move the traceback to the thread to keep the main channel neater? This behavior is because Prefect deletes are soft and batched up and executed after a certain time interval. The soft delete removes it from the UI, but not from our database so if you immediately try to create a project with the same name, you will get the uniqueness violation

```$ prefect create project veg_management

And thank you for your response, I will try again tomorrow
