TypeError: argument of type 'type' is not iterable

:question: Question about writing unit tests for a _*async*_ methods of a plugin. I’m getting this `TypeError: argument of type 'type' is not iterable` and I’m not sure why. I believe the test needs to be async as well? Full error is below and my plugin function snippet and unit test in the thread/

plugin function under test.py

unit test.py

Python trips you up.. as these `
``` (EnvironmentVarsRequest),```
are just parenthesis around a single value, and is not a tuple unless you add a trailing comma (or more elements)
``` (EnvironmentVarsRequest,),```

That was it. Tests are working as expected now :+1:

I feel like a noob but at least I’m unblocked
