Cannot Authenticate Google Analytics Reporting API with Magic Mirror Module

I am working on a Magic Mirror module. This is my first time using node and i think i did some things wrong. But i cannot figure it out anymore with google and trying things out.

I have used the Hello Analytics template, and it worked when i started. But my code was just pasted below the node code and i knew this wasn't how it supposed to be. So i rewrote the code, but now it is not working anymore. I might have made a few mistakes, but i don't get any errors on my code in the javascript console.

I'll sum up what i did:

• i created a project, and an API key for the module in the credentials app from google. i set everything up as asked by the hello analytics tutorial.
• I added the ClientID to the meta tag in the head. I placed this directly in the index.html file. I also added the other required meta tag.
• I created a view for my Analytics account and copied the view variable listed below. (the comment behind it is the Table id. as i didn't knew which one i needed.)

If the function queryReports is outside of the node framework, it works as intended and outputs data. But whenever i try to incorporate it in the node code it just throws an 401. Which means it is missing credentials to verify my user account. I have signed in with the OAuth2 button and it says i am singed in.

Can anyone tell me what i am doing wrong? Here is the code for the module:
