Question

Hello got a quick question Are there any testing examples preferably with invocation of `async` solids currently working through this and there is a `DagsterTypeCheckDidNotPass` with type failure along the lines of `expected return type got coroutine` Our tests that use `execute solid` for our async solids still work fwiw

Jordan W · Answer

basic example ``` solid async def foo async gt str return bar pytest mark asyncio async def test foo result = await foo async assert result == bar ```

we have this under test but not using the pytest scheme you are trying <https github com dagster io dagster blob master python modules dagster dagster tests core tests test solid invocation py L348 L355>

Forgot to mention yesterday but the test passed without the type annotation Once adding it it throws the type error

chris · Answer

taking a look

alex · Answer

ah type annotation that seems like what we need to repro the bug Thanks for the report edit clarity

Jordan W · Answer

yep sees type `coroutine` but expects `str` sorry if that wasnt clear

chris · Answer

I don t think type annotation is the bug I think we re getting the coroutine and not unfurling it properly
