Switched from DP to SDK and channel comes up blank after working in dev environment.

Before the holidays, I converted my old Direct Publisher channel to the SDK version using the information and tutorials posted online. In the end, I had to modify my JSON but did get it working even if the ending channel app looked and worked differently than before.  My channel update was approved and went live on January 1st.

Well, now it's not working...even though it was fine in the dev environment.  (The dev version comes up empty too.)  I thought maybe there was some bad stuff in the JSON, so I kept removing episodes and shows until I had only one show with 3 episodes left.  Stupid thing still won't load.

Anyone care to take a look?  A copy of the JSON is here: https://feeds.twit.tv/roku-test3.json

    Nevermind.  My JSON had extra commas in it that didn't show up as an error in Chrome or when running it through the JSON validator at jsonlint.com.

    I thought I had found the issue with my JSON having extra commas in it that didn't show up as an error in Chrome or when running it through the JSON validator at jsonlint.com...but that wasn't it.  I've tried cutting back the JSON to just the bare bones and it's still not displaying.

    Anyone got any ideas?  No matter what I try, this is just coming up with a blank screen.  JSON is at https://feeds.twit.tv/roku-test3.json

      The JSON feed has a hidden UTF-8 BOM marker at the beginning of it, and the BrightScript JSON parser doesn't understand.  Those are the 0xEF, 0xBB, and 0xBF characters at the start.

      Here's the output from curl piped through hexdump -C

      Try having your code strip that from the start of the string or modify the feed to not include that.

      I looked at your feed and see that there is no Categories and playlists at the bottom or any Categories and queries! I put two examples below!

      example:

       }
  ],
  "categories": [
    {
      "name": "Episodes: Latest back to 161",
      "query": "161-200",
      "order": "most_recent"
    },
    {
      "name": "Episodes: 121-160",
      "query": "121-160",
      "order": "chronological"
    },
    {
      "name": "Episodes: 81-120",
      "query": "81-120",
      "order": "chronological"
    },
    {
      "name": "Episodes: 41-80",
      "query": "41-80",
      "order": "chronological"
    },
    {
      "name": "Episodes: 1-40",
      "query": "1-40",
      "order": "chronological"
    },
    {
      "name": "Francois du Plessis and Walter Veith Series",
      "query": "FdP WV Series",
      "order": "most_recent"
    },
    {
      "name": "Francois du Plessis Series",
      "query": "Francois du Plessis Series",
      "order": "most_recent"
    },
    {
      "name": "Walter Veith Series",
      "query": "Walter Veith Series",
      "order": "most_recent"
    },
    {
      "name": "Martin Smith Sermons",
      "query": "Martin Smith Sermons",
      "order": "most_recent"
    },
    {
      "name": "Miscellaneous",
      "query": "Misc",
      "order": "most_recent"
    },
    {
      "name": "Health Series",
      "query": "Health Series",
      "order": "most_recent"
    },
    {
      "name": "Other Series",
      "query": "Other Series",
      "order": "most_recent"
    },
    {
      "name": "Music",
      "query": "Music",
      "order": "most_recent"
    },
    {
      "name": "Ellen G. White Books (audio with text on screen)",
      "query": "Ellen G. White Series",
      "order": "most_recent"
    }
  ]
}
