Nice.
But.
Shouldn't this have been detected by one of our CI tests? I'm confused.

Integration tests are using Python 3.8: https://github.com/golemfactory/yapapi/blob/master/.github/workflows/goth.yml; unit tests, typechecking, codestyle etc. are run on every OS/Python version combination: https://github.com/golemfactory/yapapi/blob/master/.github/workflows/tests.yml

as @filipgolem already said, we currently run the goth tests only on Python 3.8 ... maybe we could enable the requestor code within those tests to use other python versions but that certainly is a separate tasks which would also include scheduling when such tests should be running (nightly only?) if feasible

@filipgolem do you understand why mypy didn't detect this?

Are we using mypy like this: mypy --python-version 3.6?
f" --- {ctx.provider_name} STATE: {await ctx.get_raw_state()}" is a valid Python 3.8 expression.
