Virtual Background Tutorial not working on Local

I can’t get the virtual background tutorial to work on local. Please see console log. Any help?
All other tutorials are running.

Install steps I followed:

  1. Docker: docker run -p 4443:4443 --rm -e OPENVIDU_SECRET=MY_SECRET openvidu/openvidu-dev:2.24.0
  2. OpenViidu-Basic-Node
  3. http-server openvidu-tutorials/openvidu-virtual-background/web

You need OpenVidu PRO for this to work: Virtual Background - OpenVidu Docs
