Error message

Error while trying to retrieve access token { Error: invalid_grant at Request._callback (C:\Users\PC\Desktop\New folder\node_modules\google-auth-library\lib\transporters.js:81:15) at Request.self.callback (C:\Users\PC\Desktop\New folder\node_modules\request\request.js:188:22) at emitTwo (events.js:106:13) at Request.emit (events.js:191:7) at Request.

There are 2 common problems that cause invalid_grant errors:

  1. Your server's clock is out of sync with NTP
  2. You've exceeded the refresh token limit

I'd suggest investigating whether either of these issues could be the source of your problem.
