test_service_scenario.py test fails with syntax error

[glaubitz]

I'm currently packaging azdev for openSUSE Tumbleweed:

See: https://build.opensuse.org/package/show/home:glaubitz:branches:Cloud:Tools/azdev

The testsuite currently fails in test_service_scenario.py with a syntax error, even on Python 3.8 (since Python 3.9 and 3.10 are not recommended):
