My request url was url = " https://api.themoviedb.org/3/discover/tv?first_air_date.gte=2023-12-25&include_adult=false&include_null_first_air_dates=false&language=ja-JP&page=1&sort_by=primary_release_date.desc&vote_average.gte=0&vote_average.lte=10&watch_region=JP&with_genres=16 " and the returned response was

{
  "status_code": 11,
  "status_message": "Internal error: Something went wrong, contact TMDb.",
  "success": false
}

This also happens in discover-tv page with the following query params:

first_air_date.gte: 2023-12-25
include_adult: false
include_null_first_air_dates: false
language: ja-JP
page: 1
sort_by: primary_release_date.desc
vote_average.gte: 0
vote_average.lte: 10
watch_region: JP
with_genres: 16

It looks like the problem is with the Genre filter.
16 Comedy - presents error.
18 Drama - works without problem.
I don't know for what reason.
Let's wait for admin Travis Bell to stop by.
