API CONFLICT
Iam just trying the api for discover/movie and the server responds with the error that the id is invalid
and when inspect the credentials iam getting the message that cant get authenticated with such key

Please post the full text of the error warning here.
Are there two errors? ID and Key?

{ "success": false, "status_code": 6, "status_message": "Invalid id: The pre-requisite id is invalid or not found." }

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.

here is the fetch request iam sending
const url = 'https://api.themoviedb.org/3/keyword/keyword_id/movies?include_adult=false&language=en-US&page=1';
const options = {
method: 'GET',
headers: {
accept: 'application/json',
Authorization: 'Bearer eyJhbGciO ...... HWoX668'
}
};

fetch(url, options)
.then(res => res.json())
.then(json => console.log(json))
.catch(err => console.error(err));

This method has been deprecated. See:
https://developer.themoviedb.org/reference/keyword-movies

This method is deprecated, you should use /discover/movie instead.

It still works,
But you need to inform which keyword ID you want to search.
https://api.themoviedb.org/3/keyword/{keyword_id}/movies
Your Request does not contain the ID. See and compare:

https://api.themoviedb.org/3/keyword/keyword_id/movies?include_adult=false&language=en-US&page=1
https://api.themoviedb.org/3/keyword/210740/movies?include_adult=false&language=en-US&page=1
