How to filter complex object in Firebase?

Could you please help to filter below JSON using eventId?

{
  "-Kb2dYPV0yUXpD_1moc9": {
    "eventId": 1,
    "message": "sdfsdfsf",
    "sentOn": 1485004202943
  },
  "-Kb2etFm1xHd8sSsESeK": {
    "eventId": 1,
    "message": "shdfhsf",
    "sentOn": 1485004553847
  },
  "-Kb2etKON8nWVKS2R0sj": {
    "eventId": 2,
    "message": "shdfhsf",
    "sentOn": 1485004553853
  }
}

I'm using below URL,

https://xxxxxxxx.firebaseio.com/chats.json?orderBy="eventId"&equalTo=1

but getting constraint index field must be a json primitive error.

I want to retrieve chat objects with respect to particular event ID. I referred to the REST API, there, it was explained with simple JSON.

Please help me.

I've run into the same error before using the firebase REST api, and it was because I didn't have quotes around the value in the equalTo clause (e.g. equalTo="1")
