This code of yours builds an API Request.
Using the AXIOS tool.
What we need to know is which API Request is sent to our server.
Can you tell us what it is here?

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.

As it is probably an issue with AXIOS perhaps some of the conversations below will help.
