Even this is an error and we will work on fix, but as to fix it on your end you have defined 2 times category in your query:

 + "      category {\n"
      + "        __typename\n"
      + "        title\n"
      + "      }\n"
      + "      photo(size: MEDIUM) {\n"
      + "        __typename\n"
      + "        url\n"
      + "      }\n"
      + "      category {\n"
      + "        __typename\n"
      + "        title\n"
      + "      }\n"
