I am packaging a crewai Flow into a FastAPI endpoint that I want to run async.

When doing so, the inputs arguments I am giving in kickoff\_async() are not properly passed when the Flow state is initialized.

When I call this endpoint, sentence\_count is properly propagated into the EmailFlow State:

```auto
@app.post("/process_email")
def process_email(
    uuid: str, 
    sentence_count: int
    ):
    try:
        result = EmailFlow().kickoff(inputs={"sentence_count": sentence_count})

```

When I call this **async** endpoint, sentence\_count is **not propagated** into the EmailFlow state:

```auto
@app.post("/process_email")
async def process_email(
    uuid: str, 
    sentence_count: int
    ):
    try:
        result = await EmailFlow().kickoff_async(inputs={"sentence_count": sentence_count})

```

Why are inputs not processed properly in the context of an async call?

I have ran into this problem before with a setup similar to yours. I ended up doing this

```auto
class YourFlow(Flow[YourFlowState]):
    def __init__ (self):
        .....
        super(). __init__ ()

    def kickoff_async(self, inputs=None):
        if inputs:
            for key, value in inputs.items():
                if hasattr(self.state, key):
                    setattr(self.state, key, value)

        return super().kickoff_async()

```

This seems to work, try it and let me know how it goes
