Issue With Changing Category for Livestream via YouTube API

I am using the YouTube API to set a category of a livestream. This is what I have so far. When the code runs nothing seems to happen.

    def Setcategory(id, title):       //Rest of the function        request = youtube.videos().update(            body={"id": id,          "snippet": {"title": title,"categoryId": "17"                },            }        )        response = request.execute()        return response

I have already made sure that the correct id is being passed. That did not seem to be the issue.

I would really appreciate some advice on this.Thank you.
