Why does the ticket upload attachment endpoint return 200 even though no attachment is created?

[Max Forsman]

I am making a request to https://$namespace.atlassian.com/rest/api/2/issue/$KEY/attachment, and I get a 200 OK response with an empty body, but no attachment is added.

Please fix this, you need to provide an informative error message when an attachment upload fails instead of just returning 200.

If you're referring to this endpoint it should return a response if successful. Take note that it can be accessed anonymously too, so you have to ensure that you've done proper authentication to the resource to remove any ambiguity in the request.
