This is great! But I'm unsure how to consume the HLS stream when using the new fission server. When I try to hit /live/STREAM_KEY/index.m3u8, nothing is there, and the directory is empty on my server. Here's my config, if anyone has any ideas I would greatly appreciate it.

{
  rtmp: {
    port: 1935,
    chunk_size: 60000,
    gop_cache: true,
    ping: 30,
    ping_timeout: 60
  },
  http: {
    port: 8000,
    mediaroot: './media',
    allow_origin: '*'
  },
  fission: {
    ffmpeg: process.env.FFMPEG_PATH || '/usr/bin/ffmpeg',
    tasks: [
      {
        rule: "live/*",
        model: [
          {
            ab: "128k",            
            vb: "1500k",
            vs: "720x1280",
            vf: "30",          },
          {
            ab: "64k",
            vb: "1000k",
            vs: "480x854",
            vf: "24",
          },
          {
            ab: "32k",
            vb: "600k",
            vs: "360x640",
            vf: "20",
          },
        ]
      },
    ]
  }
}

everything looks good when the stream connects:
