Cloudkit Web Service Query BadRequestException

Question

I'm trying to query CloudKit for a simple object where the name equals a string but I am getting back a BadRequestException.

The RecordType is "Teacher" with parameters "Name" and "Grade".

I'm guessing there is something wrong with my query filter but can't find anything out of spec for Apple's reference.

    {"query": {
          "filterBy": {
             "fieldName": "Name", "fieldValue": {
               "type": "STRING", "value": {
                "Name": "Teacher 1"
                }
              }, 
              "comparator": "EQUALS"
           }, 
        "recordType": "Teacher"
     }, 
   "zoneID": {"zoneName": "_defaultZone"}
}

Resulting Error:

{u'serverErrorCode': u'BAD_REQUEST', u'reason': u'BadRequestException: Invalid value, expected type STRING but actual value was object of class com.apple.cloudkit.ws.application.common.data.UnknownTypeModel', u'uuid': u'c254448d-130e-4c6c-8170-554d976a1789'}

Answer 1

You do not need to put the field name in again, as "Name" is already set in the "fieldName" parameter. In fieldValue, it only needs to be {"value":"Teacher 1"}.

(The inspiration to the solution came from CloudKit JS Sample Code Error).
