401 response when asking for user's profile but access token works for other request

My Question or Issue

I am working on a web app and I need to access the user's profile information to learn if they have a premium account. The access token I have been using already has the scope needed for this request, but when I run the request for the profile information, it returns a 401 error. It tells me that my access token is unauthorized. I have no idea why it is sending me this error response when it works for a different request. 

I will attach the code in the attachments. Any help is appreciated.

Since the Client Credentials flow does not include authorization, only endpoints that do not access user information can be accessed. Therefore, in this case, you should use a different Authorization method that lets you log in.
