I suppose you made an API Request like this:
https://api.themoviedb.org/3/tv/popular?api_key=THE_KEY&language=en-US&page=1
The first result for me was "The Flash".
With this backdrop_path

backdrop_path "/jC1KqsFx8ZyqJyQa2Ohi7xgL7XC.jpg"

Can you inform or post here which backdrop_path is not working for you?

The whole first page backdrop_path is not working for me. I am trying to use it in xcode and giving me an error saying that data doesn't exist and when change the url to page 2 and try to fetch backdrop_path data it works perfectly

I already understood that the ones on page 1 didn't work.
And that only those on page 2 were OK.
It remains to be seen whether:
1 - It is an error here from the TMDb API, which is sending you an error response especially
or
2 - It may be an error on your side, in your programming, in xcode.

And how should we proceed to find out where the error is?
First I did this same research, which I suppose you did.
And for me the backdrop_path on page 1 is working correctly.

So I asked you to post here one of the backdrop_path on your first page, which is not working.
So, can you do this?

I can open those backdrop_path from link you have provided I have already tired that and see that work. so I think it might probelm with my programming but it works for page 1 onwards so i though that it was issue withe TMDb but i am not sure what the issue is if you wnat i can provide you my code and see whats wrong

I don't think it will solve it because I don't know anything about xcode.
If the problem is in your programming, and I think so, then you better get help from programmers who know xcode.
