Android/Firebase - Error while parsing timestamp in GCM event - Null timestamp

Question

I\'m building an Android app which will receive push notifications. I\'ve got Firebase Cloud Messaging setup and pretty much working, such that I can send the following payl

Answer 1

Format below (no notification body, nor are there any arrays) fixed the timestamp exception for me:

{
  "to": "eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee",
  "data":  {
      "message": "message",
      "title": "hello",
  }
}

Tested fine with http://pushtry.com/

The only reason I included the long 'eeee...' is that is the exact size of my token.
