sync-engine not syncing inbox, calendar events on Google/Gmail

[themanojshukla]

I'm running the nylas sync engine via bin/inbox-start --prod. I also have successfully authenticated gmail account with it by bin/inbox-auth <mymailid>@gmail.com. But I'm not able to see any messages, or events. The DB also has empty rows in message table in all shards.

Am I missing anything?
