[Python] How do I get around a typing issue for execute_workflow in PyCharm

I have a test that has code that executes a workflow which PyCharm marks as incorrect (pyright doesn't complain)

result = await workflow_client.execute_workflow(
SayHelloWorkflow.run,
req,
id="say-hello-test",
task_queue=task_queue
)


It is getting this type error:

Unexpected type(s): ((request: MyReq, Any) -> Coroutine[Any, Any, MyResp], MyReq, str, str)

Possible type(s): (MethodAsyncSingleParam[SelfType, ParamType, ReturnType], MyReq, str, str) (str, Any, str, str)
​

SayHelloWorkflow is defined as

@workflow.defn
class SayHelloWorkflow:
@workflow.run
async def run(
self, request: MyReq
) -> MyResp:

return await workflow.execute_activity(
"SayHello",
request,
start_to_close_timeout=timedelta(seconds=10),
)
