Error occurs when starting p4runtime-shell: No module named 'google.protobuf'

I built the docker image and tried to run p4runtime-shell with the provided python script p4runtime-sh-docker. The script generates the following error and does not start p4runtime-shell.

Traceback (most recent call last):

ModuleNotFoundError: No module named 'google.protobuf'

I found that protobuf==4.21.4 was getting installed. Setting it to an earlier version, 3.17.3, in setup.py removes the error.
