There was a syntax issue on how to pass cmd parameters. I was able to resolve the issue by modifying my cmd as below.

Before -

[root@fed32 ~]# buildah config --cmd '["/usr/bin/python3.8", "manage.py", "runserver"]' fedora-working-container

After -

[root@fed32 ~]# buildah config --cmd '"/usr/bin/python3.8" "manage.py" "runserver"' fedora-working-container
