node js with gmail api, The API returned an error: Error: unauthorized_client

Question

Edit: The error is happening on on this piece of code:

   var gmail = google.gmail(\'v1\');
      gmail.users.labels.list({
        auth: auth,
        userI         


        

Answer 1

I did a console.log on TOKEN_PATH, it gave me the path of where the file was.

I had to delete the file

/Users/user/.credentials/gmail-nodejs-quickstart.json

which was a hidden folder I could not find on my mac.
