WebApp fails to start due to tenacity version upgrading to 8.4.0 - 8.4.1 ( previously working version was tenacity 8.3.0 )

Bug Details

A deploy of the accelerator fails due to the backend app not having a requirements.txt file entry fixing the version of tenacity
i.e.
tenacity == 8.3.0

in file:
app/backend/requirements.txt

the error is as below

1. Deploy the app from a codespace and wait for the final restart of the WebApp.

What is the expected behavior?
WebApp to start.

A current workaround is to add to the requirements.txt located at app/backend/requirements.txt an entry:
tenacity == 8.3.0
