Error when using Web streaming with Omniverse

Omniverse Core Platform

I am following the readme file here with the latest code from the main branch. I want to build a USD viewer kit application that streams to the provided react application. I am running this in an Nvidia Omniverse Workstation in Azure.

When I open the react application in the browser and select ‘UI for default streaming USD Viewer app’, I see the following error in the kit application’s logs

main: thread_init: already added for thread

What could be wrong?

Hi, I’m having the same problem.
I’m using USD composer_streaming.kit and have referenced WebRTC streaming - #7 .

Any solutions are available?
