Parse cloud query returns null result - objective-c

Question

I have the following cloud function
Parse.Cloud.define("test", function(request, response) {
Parse.Cloud.useMasterKey()
var query = new Parse.Query("Verification");
query.equalTo("objectId", "lHBL87Sg2H");
query.find({
success: function(results)
{
response.success(results[0].get("objectId"));
},
error: function()
{
response.error("failed");
}
});
})
I call this cloud function in Objective C with the following code,
[PFCloud callFunctionInBackground:#"test"
withParameters:nil
block:^(NSString *result, NSError *error) {
if (!error) {
NSLog(#"%#",result);
}
}];
The result of this call is (null).
The parse log shows the following record
I2015-04-20T20:07:29.383Z] v81: Ran cloud function test1 for user zOpfIOyZQ1 with:
Input: {}
Result: undefined
I also tried the promise but the output is still null.

To get an object given its id, use Query.get() as follows ...
Parse.Cloud.define("test", function(request, response) {
Parse.Cloud.useMasterKey();
var query = new Parse.Query("Verification");
query.get("lHBL87Sg2H").then(function(object) {
var objectId = object.id;
var someAttribute = object.get("foo");
response.success({"the id is":objectId, "foo is": someAttribute});
}, function(error) {
response.error("error " + error.message);
});
});
