iOS facebook graph batch request first request doesn't work - facebook

Question

I have 3 chained requests: 1.fbRequest and 2.meRequest are identical. 3. thirdPartyIdRequest
meRequest and thirdPartyIdRequest are dependent on fbRequest.
When this runs, every time fbRequest returns a null response dictionary while meRequest(which is an identical call called a second time) and thirdPartyIdRequest return valid responses. I'm not sure why this is happening.
NSDictionary *dictionary = #{#"fields": #"id, first_name, middle_name, last_name, email, picture.type(large)"};
NSDictionary *dictionaryThirdPartyIdRequest = #{};
FBSDKGraphRequest *fbRequest = [[FBSDKGraphRequest alloc] initWithGraphPath:#"me" parameters:dictionary HTTPMethod:#"GET"];
FBSDKGraphRequest *meRequest = [[FBSDKGraphRequest alloc] initWithGraphPath:#"me" parameters:dictionary HTTPMethod:#"GET"];
FBSDKGraphRequest *thirdPartyIdRequest = [[FBSDKGraphRequest alloc]
initWithGraphPath:#"custom_audience_third_party_id"
parameters:dictionaryThirdPartyIdRequest
HTTPMethod:#"GET"];
FBSDKGraphRequestConnection *connection = [[FBSDKGraphRequestConnection alloc] init];
//request me
[connection addRequest:fbRequest
completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
//TODO: process me information
NSLog(#"result fbRequest %#",(NSDictionary *)result);
} batchEntryName:#"fbRequest"];
//request addRequest:thirdPartyIdRequest ok
[connection addRequest:thirdPartyIdRequest
completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
//TODO: process like information
NSLog(#"result thirdPartyIdRequest %#",(NSDictionary *)result);
} batchParameters:#{#"depends_on" : #"fbRequest"}];
//request me ok
[connection addRequest:meRequest
completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
//TODO: process like information
NSLog(#"result meRequest %#",(NSDictionary *)result);
} batchParameters:#{#"depends_on" : #"fbRequest"}];
[connection start];
