The request get hit to server but it does not take any parameter or file with it, i double checked it file url and parameters dic is not empty

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:[NSString stringWithFormat:@"com.app316.MWPl.backgroundconfiguration"] ];
configuration.sharedContainerIdentifier=kGroupNameToShareData;

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

AFHTTPRequestSerializer *serializer = [AFHTTPRequestSerializer serializer];

    //parameters is NSDictionary With values in it
   NSMutableURLRequest *requesting=[serializer requestWithMethod:@"POST" URLString:urlString parameters:parameters error:&error99];

 NSURLSessionUploadTask *uploadTask4 =[manager uploadTaskWithRequest:requesting  fromFile:storeURL progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error)
    {
        if (error)
        {
            NSLog(@"Error: %@", error);
            NSLog(@"Responce== %@", response);
            NSLog(@"Success: =%@", responseObject);
        }
        else
        {
            NSLog(@"Success: %@ %@", response, responseObject);
