Mention any other details that might be useful.

the command updates the runtime version to python 3.7 and fails. The second time I run the command (only if I leave the runtime in 3.7) the deployment works. If I set it back to python3.8 it continues failing I can automate the deployment with CI\CD on push with github actions and leave the runtime in python 3.8
