Search endpoint
the search endpoint appears to be returning empty 200 responses for all queries.

I just tested it and it worked fine.
But another user is having the same problem.

Problems with API Request

In order for someone to help you with API Request questions,
it is critical that you post here the API Request you are sending to the TMDb server.
Remember to replace your Key with MY_KEY , YOUR_KEY , THE_KEY , or something like that.

Not the programming code/script you used to build the API Request.
But the API Request that is sent to the TMDb server.
Or the API Request you would like to send.

Example

https://api.themoviedb.org/3/search/multi?api_key=THE_KEY&query=Aurora&include_adult=false&language=en-US&page=1  
https://api.themoviedb.org/3/search/multi?query=Aurora&include_adult=false&language=en-US&page=1

agree fixed for me too now thanks!
