I have a simple web transaction using fast api to test APM. The code is the following:

```auto
app.get("/critical", status_code=500)
def critcal_failure():
    try:
        print("Doing something critical")
        raise Exception("something went wrong")
    except Exception as e:
        apm_client.capture_exception(exc_info=True)
        raise HTTPException(status_code=500, detail=f"{e}")

```

I would expect this to have the "events.outcome" field set to failure. Instead I see it to be "success". Am I missing something?  
ELK stack version is 7.17.9

Hi @avlachopoulos

I copied your example code verbatim (except for adding the missing `@` in front of `app`), and `outcome` is set to `failure` as expected.

Could you share the output of `pip freeze`? Maybe it's a version problem.

Also, note that your handling of the exception and calling `capture_exception` isn't necessary, the agent should capture unhandled exceptions automatically.
