  await handleErrorCode(mediaResponse);

  const mediaResponseBody: IXMediaPost = await mediaResponse.json();

  return mediaResponseBody;
};

handleError code just check if the status is an error and prints the text, but essentially the API is returning an unable to authenticate you error 32. Tried on insomnia with the same headers etc.. get the same result

enter image description here

These are the permissions that i’m requesting, so nothing should be missing. Kinda lost here so would appreciate any help

Am expecting the API to return a 2xx code and return a media_id. Have tried following a bunch of tutorials, reading the guides etc.. but nothing seems to be working
