Can't remux HLS: MediaRoot:undefined cannot be written.

Hello I am able to push but when I try to enable HLS I get this error:
[ERROR] Node Media Trans Server startup failed. MediaRoot:undefined cannot be written.

trans: {
    ffmpeg: '/snap/bin/ffmpeg',
    tasks: [
      {
        app: 'live',
        hls: true,
        hlsFlags: '[hls_time=2:hls_list_size=3:hls_flags=delete_segments]',
        hlsKeep: true, // to prevent hls file delete after end the stream
      }
    ]
  }
