AFNetworkingErrorDomainCode 1011

When ever i hit on my API too fetch some data it always gives me this Error.

Error Domain=AFNetworkingErrorDomain Code=-1011 "Request failed:
internal server error (500)"

UserInfo={AFNetworkingOperationFailingURLResponseErrorKey= { URL: }

I have google for this question and they all replied with this solution that i should set response serializer to JSON.
But i already have set it.

Here is my code.

-(void)userHasCheckThisStoreDealsWithStoreName:(NSArray *)data {
NSString *storeName = [data objectAtIndex:0];
NSString *branchName = [data objectAtIndex:1];
NSString *userID = [data objectAtIndex:2];
NSString *check = [data objectAtIndex:3];
NSLog(@"Store Name: %@",storeName);

NSDictionary *param = @{@"user_id":userID ,@"s_name":storeName , @"branch_name":branchName, @"enter_flag":check};

[BabyNetworkManager postWithUrlString:@"" parameters:param success:^(id data){

NSError *error;
NSDictionary *responseDictionary = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:&error];;
NSLog(@"Dictionary = %@",responseDictionary);
if ([[responseDictionary objectForKey:@"status"] isEqualToString:@"success"]) {

NSArray *arrayOfParamObjects = [NSArray arrayWithObjects: storeName,userID,branchName,check, nil];
[self performSelectorInBackground:@selector(userHasCheckThisStoreDealsWithStoreName:) withObject:arrayOfParamObjects];


} failure:^(NSError *error){

NSLog(@"Error %@",error);



Please do read the comment i have mentioned in line number 3 of below function.

+(void)postWithUrlString:(NSString *)urlString parameters:(NSDictionary *)parameters success:(HttpSuccess)success failure:(HttpFailure)failure{

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];// I have check this line by commenting and uncommenting in both state i get the same error
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json",@"text/json",@"text/javascript",@"text/html", nil];

[manager POST:urlString parameters:parameters success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject){

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error){




HTTP 500 is the server error, I guess this error is caused by the invalid post param you have sent to the server, and some exception occurred in server side.

Because I have tried your API in OC, I can get the correct JSON response. Here comes the sample code:


#import "ApiClient.h"

@implementation ApiClient

+ (instancetype)sharedClient
    static ApiClient *_sharedClient;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _sharedClient = [[ApiClient alloc] initWithBaseURL:[NSURL URLWithString:@""]];

        _sharedClient.securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeNone];

    return _sharedClient;



#import "ViewController.h"
#import "ApiClient.h"

@interface ViewController ()


@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    NSDictionary *param = @{@"user_id":@"123" ,@"s_name":@"123" , @"branch_name":@"123", @"enter_flag":@"123"};

    [[ApiClient sharedClient] POST:@"/api/v8/fencerecorddata" parameters:param constructingBodyWithBlock:nil progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        NSLog(@"%@", [responseObject description]);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"%@", [error localizedDescription]);



Here is the Console log:
