Error 401: "Unauthorized" "invalid oauth token" when requesting user information

Hm already tried that … didn´t work as well.

Now i tried it with exactly your code and the result is:

{error: “Bad Request”, status: 400, message: “No client id specified”}

If i use no Client-ID in the Header

{error: “Unauthorized”, status: 401, message: “invalid oauth token”}

If i add the Client-ID to the Header
