live stream lifecycle not working

I want to get the video uid to display the stream, but the lifecycle endpoint always gives this response

{
  isInput: true,
  videoUID: null,
  live: false,
  status: 'disconnected',
  chunked: true
}

{
  isInput: true,
  videoUID: null,
  live: false,
  status: 'disconnected',
  chunked: true
}
