@app.get("/")
def return_id(my_id: int):
     return my_id

Description

Problem

We receive our backend errors on Sentry. However, we would like to filter out the errors that are sent using their status_code.
We found 2 promising leads in sentry-python, which are before_send function that allows to alter the events before sending them, and traces_sampler argument in the sentry_sdk.init, which allows us to filter some events.

However, the status_code seems to appear nowhere: we checked on Sentry and in the code, and the error events that are formed do not seem to pass this information.

Expected behavior

The event caught by sentry contains a status_code. The error is sent as normal, but as I have the status_code, I can drop the sentry event.

Another solution could be to configure from fastAPI what HTTPExceptions are sent to sentry, but we could not find how to achieve this neither.

How to reproduce

(with sentry configured)
Call the endpoint, pass a string as my_id instead of an int. In Sentry, you get an error. There's no way of telling it's a 422.

I am not well versed in sentry's sdk but the docs seem to indicate that you should be able to access the original exception in the hint param which should contain the status code

What does your hint param look like for a sample request?
