[Evolution] Evolution Tasks Error

[Pramathesh Ambasta <pramathesh nregaconsortium in>]

Hi

I am running Evolution 3.12.7 on Ubuntu 14.10.

I keep getting this error when I click Tasks:

Unable to connect to 'Tasks': Cannot open calendar: Authentication required: {
"error": {
  "errors": [
   {
    "domain": "global",
    "reason": "insufficientPermissions",
    "message": "Insufficient Permission"
   }
  ],
  "code": 403,
  "message": "Insufficient Permission"
}
}

The other error I get is:

Unable to connect to 'Tasks': Cannot open calendar: Data source 'Tasks' does not support OAuth 2.0 authentication

I suppose  this error is related to the first error message? In which case is there a way to enable OAuth with evolution?

Also, while the message says that Evolution cannot open calendar, it does. I am able to see my google calendar very well.

Thanks in advance
