Conforming Fire App Builder recipe code to Roku JSON feed

Question

I have a Roku channel with multiple series, seasons and episodes. I am attempting to modify my Fire App Builder recipes to extract the desired data according to the structure of my Roku feed. Unfortunately when I launch my app, it gets stuck on the loading splash screen. I am new to coding and not sure if I have correctly coded the recipes and would appreciate any input. Here is a sample of my feed and both category and content recipes code. The full feed can be found here: https://d2n971lt6fos4i.cloudfront.net/Feed/Nation+Extreme+Wrestling.json. Any suggestions?

Roku JSON feed sample:

            },

NEWCategoriesRecipe.json

NEWContentsRecipe.json

{

  "model": "com.amazon.android.model.content.Content",
  "translator": "ContentTranslator",
  "modelType": "array",
  "query": "$[?(@.series.seasons[0] in [$$par0$$])]",

    "episodes/releaseDate@mReleaseDate",
    "episodes/rating/rating@mRating",
    "episodes/longDescription@mLongDescription"
  ]
}

I tried to modify the recipe code to what I thought was the proper path, but the app stuck on the loading screen.
