Describe the bug

It appears that the issue from #197 still persists.

To Reproduce

Steps to reproduce the behavior:

Create DB:

Try to add region to DB:

astra db create-region my_serverless_db -r us-east-2

Using database ID produces same error:

astra db create-region 26054aa9-eb37-4d88-b343-7c934cd1d7bc -r us-east-2
