This issue I believe should be escalated and its severity raised.
We've confirmed that the bulk API /dataservice/data/device/state/Interface?count=count does in fact NOT contain interfaces for cEdge devices.
Existing client monitoring applications that rely on this endpoint no longer have visibility of [some] interfaces.
Using real-time endpoints may not be practical as a workaround. For example it may take too long to query 100's or 1000's of devices. In fact, we were explicitly instructed by Viptela/Cisco NOT to use real-time interfaces to acquire bulk data due to resource concerns.
Example
Using the Cisco DevNet system (Cisco 4D Secure SD-WAN (Viptela) Single DC v3.3) we see cEdge devices listed under /dataservice/device, but no cEdge interfaces listed under /dataservice/data/device/state/Interface.
