NSURLSessionConfiguration and NSData always returning nil

I am new to Mac application development and i am working on fixing the deprecation issues present in the application. I am using XCode 11.3 in Mojave MacOS 10.14 and Our application contains the following line of code

[NSURLConnection sendSynchronousRequest:request returningResonse:response error:Error]

A warning message getting displayed as sendSynchronousRequest is deprecated and it is suggesting to use [NSURLSession dataTaskWithRequest:completionHandler:] .

so i have implemented the following code

NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: nil delegateQueue: [NSOperationQueue    mainQueue]];
NSURL * url = [NSURL URLWithString:@"MyURLHere"];
NSMutableURLRequest * urlRequest = [NSMutableURLRequest requestWithURL:url];    
[urlRequest setHTTPMethod:@"POST"];
[urlRequest setHTTPBody:[params dataUsingEncoding:NSUTF8StringEncoding]];
NSURLSessionDataTask * dataTask =[defaultSession dataTaskWithRequest:urlRequest
                                    completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
                                      NSLog(@"Response:%@ %@\n", response, error);
                                      if(error == nil)
                                      {
                                          NSString * text = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
                                      }
                                  }];
[dataTask resume];

i found that data is being returned as nil always. When i debugged the code, i found that even [NSURLSessionConfiguration defaultSessionConfiguration] is being returned as nil. Can you please suggest what needs to be done in order to fix these issues?
