Facing an issue with the Roku direct publisher feed?

I am creating the JSON feed for one live HLS stream.

Here is my JSON feed.

{
  "providerName": "Provider Name",
  "language": "en",
  "country": "US",
  "content": {
    "dateAdded": "2023-12-15T00:00:00Z",
    "movies": [
      {
        "title": "Live Stream",
        "content": {
          "dateAdded": "2023-12-15T00:00:00Z",
          "videos": [
            {
              "url": "https://liveStreamurl.com/test.m3u8",
              "quality": "HD",
              "videoType": "HLS"
            }
          ]
        }
      }
    ]
  }
}

I uploaded this JSON on Roku Direct Publisher. But it shows under-processing. Like below

Can anyone suggest what was wrong here?. Is there any field missing from my JSON?
