Azure Marketplace - Unreal Engine Pixel Streaming

The default Signaling Server deployed by Azure Marketplace deployment is not working for me. It instantly disconnects and crashes the video game with the error ‘streamer disconnected: 4000 - failed to parse answer’s SDP’. The only fix i found was updating the app.js with the fix found here: Pixel Streaming not working in Chrome version 89 - Development / Programming & Scripting - Epic Developer Community Forums (unrealengine.com) which is adding offer.sdp = offer.sdp.replace(“a=extmap-allow-mixed\r\n”, “”) to the SetupWebRTCPlayer. Why is this necessary? My Chrome and MS Edge is fully updated. I would like to avoid customizing the web server deployment for this. Is this an outstanding bug in the default version or perhaps some other issue I have in my game or other deployment settings.

Thanks!
