Hi, i have this today. yestarday it worked but not today, my 2nd get -
https://api.themoviedb.org/3/search/movie?api_key=THE_KEY&query=${searchTerm}
is working well, but not this one :
https://api.themoviedb.org/3/movie/${movieId}?api_key=THE_KEY

I tested your API Request in my browser and it worked without any problems.
Test yourself too to confirm my OK result.

https://api.themoviedb.org/3/movie/550?api_key=THE_KEY  

I was unable to reproduce the error.
See the list of TMDb server error warnings here.
https://www.themoviedb.org/documentation/api/status-codes
In your case:

Code    HTTP    Message  
6       404     Invalid id: The pre-requisite id is invalid or not found.  
37      404     The requested session could not be found.  

TMDb server error 404 should probably be 6.
Can you let us know which of these error responses you received?

If this is true, probably the ID used must have something else or be in error.
Maybe it's a code error.

Or else this 404 error is being reported by your code/tool and not by the TMDb server.

PS: It's not a good idea to give out your API Key. I changed it to THE_KEY

Or else it could be a problem generated by AXIOS.
In that case, see the links below.
