Event Schema Inside Eventstream Never Matching

Gotcha. Appreciate that.

Turns out though, the issue isn't a mismatch. As I suspected, the fields match. The problem is that I am not sending the required headers, which unfortunately are not yet documented by Microsoft. The Event Schemas use the Cloud Events spec, so we need to send ce_type and a few others. My contact at MS is working on getting a list of which headers are required.

Okay so for anyone else stumbling on this. If you are trying to use Event Schemas inside event streams, you basically can't yet. There are HTTP headers that are required, and they are currently undocumented. I am working with Microsoft now to get a list of the required headers, and I'll update this post when I get that.
