As mentioned in other similar topics, there is currently a rather constraining issue when making an API request. Indeed, sometimes the response is mixed and has no coherence with the expected answer. Below is an example by making a request to the following endpoint:

https://api.themoviedb.org/3/movie/64212?append_to_response=credits,release_dates,changes&end_date=20240706&start_date=20240704&language=fr-FR

This does not happen systematically every time; it is quite random...
