mapJsonResult fails on "belongs_to_collection" parsing

[RafaelPereiraa]

When you try to fetch info of some old movies, it works like a charm because all of them returns "null" on the field "belong_to_collection".

e.g. movie 5353, the hunting party (the one from the readme)

{
  "adult": false,
  "backdrop_path": "/cN6GW2y4m7lEuc5t5ahafgAQRbN.jpg",
  "belongs_to_collection": null,
  "budget": 15000000,
  "genres": [
    {
      "id": 28,
      "name": "Action"
    },
    {
      "id": 12,
      "name": "Adventure"
    },
    {
      "id": 53,
      "name": "Thriller"
    },
    {
      "id": 18,
      "name": "Drama"
    }
  ],
  "homepage": "http://www.thehuntingpartymovie.com/",
  "id": 5353,
...
}

But if you try to fetch any newer movies, like Dune 2:

{
  "adult": false,
  "backdrop_path": "/xOMo8BRK7PfcJv9JCnx7s5hj0PX.jpg",
  "belongs_to_collection": {
    "id": 726871,
    "name": "Dune Collection",
    "poster_path": "/wcVafar6Efk3YgFvh8oZQ4yHL6H.jpg",
    "backdrop_path": "/ygVSGv86R0BTOKJIb8RQ1sFxs4q.jpg"
  },
  "budget": 190000000,
  "genres": [
    {
      "id": 878,
      "name": "Science Fiction"
    },
    {
      "id": 12,
      "name": "Adventure"
    }
  ],
  "homepage": "https://www.dunemovie.com",
  "id": 693134
...
}

it does not have a class to map it, resulting in:

java.lang.RuntimeException: info.movito.themoviedbapi.tools.TmdbException: com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize value of type `java.lang.String` from Object value (token `JsonToken.START_OBJECT`)

I didn't checked if there is any more missing fields.

Hi, thanks for reporting this. I'll try to get a fix & new release out this evening.

Seems the api documentation for "belongs_to_collection" is incorrect. It is listed as a string, but returns a json object.

Version 2.0.3 has been released, please use this and the problem should be fixed :)
