Bug: Unable to set default `extra` on exception

[umarbutler]

Description

Using the below code to define a custom exception does not let the extra field be returned in responses where the error is raised:

class InvalidApiKeyError(NotAuthorizedException):
    detail = "Invalid API key"
    extra = "The API key you provided is invalid, incorrect, expired, has been revoked, or your account is overdue."

The below code doesn't work either:

class InvalidApiKeyError(NotAuthorizedException):
    detail = "Invalid API key"

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.extra = "The API key you provided is invalid, incorrect, expired, has been revoked, or your account is overdue."

class InvalidApiKeyError(NotAuthorizedException):
    detail = "Invalid API key"

    def __init__(self, *args, **kwargs):
        super().__init__(
            *args,
            **{
                "extra": "The API key you provided is invalid, incorrect, expired, has been revoked, or your account is overdue."
            }
            | kwargs,
        )

This doesn't work either. Is extra just ignored when the status code is 5XX?

🤦 This one is my bad, I set a default exception handler for debugging purposes and forgot I had set it.

[umarbutler]

I'm reopening this because it turns out this does actually happen even without that custom exception handler 😆

However, this does work as a workaround:

class InvalidApiKeyError(NotAuthorizedException):
    detail = "Invalid API key"

    def __init__(self, *args, **kwargs):
        super().__init__(
            *args,
            **{
                "extra": "The API key you provided is invalid, incorrect, expired, has been revoked, or your account is overdue."
            }
            | kwargs,
        )

(As well as the other workarounds)
