I was facing the same error while creating my container. I solved the error by using the exact version of my Python venv i.e. 3.8.9

Earlier for the image, I was using 3.8-alpine for a lighter version of the image. But, it wasn’t working out for me and got the same error as yours.

Hope this helps! Thanks.

For now the issue has been resolved by removing backports.zoneinfo from requirement.txt. App seems to work fine after removing this library :)

Not an intelligent solution, but it works and take me to the next roadblock
