422 Unprocessable Entity for app_home_opened

[GH-maggio]

I am unable to process app_home_opened events, getting 422 errors. I am able to process 'message.im' events fine. Is there an issue with the incoming payloads on these two being different?

Issue is the slack event app_home_opened does not have the authed_users field. Work around is to comment this out in model.py for now.

Hi Chris,
Thanks for getting in touch about this. I'm not sure we can answer this question since you're using a third-party library, and the validation in that library is what caused the event callback to get rejected.
Therefore, it seems like something the library author would need to answer, and it seems you've already sent that question (or a similar one) to them: #10
Hopefully they can confirm whether or not a future payload change will be an issue. Thanks for checking with them.

I'll generate a pull request for the following change to models.py:

authed_users: Optional[List[str]]

@GH-maggio Thanks, I'll review the pull request.
