That looks like something client side as a number of the values you have in your response are not values that we return on the API. For example:

'adult': False,
'backdrop_path': None,
'genre_ids': ['Drama'],
'video': False,
'vote_average': 10,

We don't return False, None integers for vote_average, or an array of string genres.

I used the discover movie end:

https://api.themoviedb.org/4/discover/movie?api_key=MYAPIKEY&language=en-US&sort_by=popularity.desc&include_adult=false&include_video=false&page=<ALLPAGES>&with_original_language=ru&with_watch_monetization_types=flatrate

I don't remember the page number, though.
