While trying to featch the data using

http://api.themoviedb.org/3/tv/46648?api_key=#########&append_to_response=external_ids,videos,release_dates,reviews,credits,recommendations,similar

It is providing all expected response but on similar part, it it giving me null data and app is crashing because I am expecting data which should at least show empty data if not available. but it is throwing me no data of similar but only recommended.

{

  "backdrop_path": "/2Ahm0YjLNQKuzSf9LOkHrXk8qIE.jpg",
  "original_language": "en",
  "original_name": "True Detective",
  "overview": "An American anthology police detective series utilizing multiple timelines in which investigations seem to unearth personal and professional secrets of those involved, both within or outside the law.",
  "popularity": 26.485,
  "poster_path": "/aowr4xpLP5sRCL50TkuADomJ98T.jpg",
  "production_companies": [....],
  "seasons": [....],
  "status": "Returning Series",
  "type": "Scripted",
  "vote_average": 8.3,
  "vote_count": 1353,
  "external_ids": {...},
  "videos":{....},
  "reviews": {....},
  "credits": {....},
  "recommendations": {...}

}

here I can not get similar result as expected.

Also what is most unusual is the same API response from 2 different devices gives two different data.

http://api.themoviedb.org/3/movie/570670?api_key=######&append_to_response=external_ids,videos,release_dates,reviews,credits,recommendations,similar

gives response with similar block also without similar block
