What to send as beaconsData to getActionsForBeacons (Kontakt beacons)

Question

I am using Kontakt beacons and iOS SDK and my code is again and again crashing at the part to get Actions for my beacons

Kontakt SDK docs are here

- (void)locationManager:(KTKLocationManager *)locationManager
        didRangeBeacons:(NSArray *)beacons {

    NSMutableDictionary *beaconsData = [NSMutableDictionary new];
    for (CLBeacon *beacon in beacons) {
        KTKBeacon *beaconData = [self _getDataForBeacon:beacon];
        if (beaconData) [beaconsData setObject:beaconData forKey:beacon];
    }
    self.actionManager = [KTKActionManager new];
    self.actionManager.delegate = self;
    [self.actionManager processBeacons:beacons withData:beaconsData];
}

The method to get beacon Data

-(NSDictionary *)_getDataForBeacon:beacon
{
    NSLog(@"%@",beacon);
    NSData * jsonData = [NSData dataWithContentsOfURL:[NSURL
                                                       URLWithString:@"****"]];
    NSError * error=nil;
    NSDictionary *dic = [NSJSONSerialization
                         JSONObjectWithData:jsonData options:kNilOptions error:&error];
    NSLog(@"%@",dic);

    NSArray *array = [NSArray arrayWithObject:beacon];
    NSDictionary *data = [self.client getActionsForBeacons:array changedSince:0 error:&error]; //##It crashes here##
    NSLog(@"%@",data);

    return data;
}

The contents of dic dictionary

{
  "id" : "42152577-e3d2-4687-b499-8112402b2ca2",
  "major" : 56809,
  "txPower" : 3,
  "browserActions" : [

  ],

    "users" : [

    ],
    "priv" : true,
    "beacons" : [

    ],
    "lat" : null,
    "beaconsCount" : 1,
    "lng" : null,
    "coverType" : null,
    "name" : "Home"
  },
  "contentActions" : [
    {
      "actionType" : "CONTENT",
      "beacon" : null,
      "distance" : null,
      "id" : "b0897c61-55c3-49c9-9f23-538f279ca1ce",
      "owner" : {
        "venues" : [

        ],
        "password" : null,
        "active" : false,
        "id" : "307d0ef9-7207-47ec-980f-9382cff9b773",
        "company" : {
          "id" : "c95cc0fc-70fb-4a82-960c-c91845654fc8",
          "name" : "Shubhank Gaur",
          "key" : null
        },
        "email" : "shubhank008pp@gmail.com",
        "salt" : null
      },
      "contentType" : "image\/jpeg",

      "impairmentTypes" : [

    }
  ],
  "proximity" : "f7826da6-4fa2-4e98-8024-bc5b71e0893e",
  "name" : "Kontakt",
  "actionsCount" : 1
}

And finally here is the error

You might have resolved this as its too late. But below is the full code which you need to get the beacon data, might be useful for others running into this.

-(KTKBeacon *)_getDataForBeacon:(CLBeacon *)beacon
{
    NSString *strURL = [NSString stringWithFormat:@"https://api.kontakt.io/beacon?proximity=%@&major=%@&minor=%@",
                        [beacon.proximityUUID UUIDString],
                        beacon.major,beacon.minor];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:strURL]];
    [request setValue:@"YOUR_API_KEY" forHTTPHeaderField:@"Api-Key"];
    [request setValue:@"application/vnd.com.kontakt+json; version=2" forHTTPHeaderField:@"Accept"];
    NSData *jsonData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    NSError * error=nil;
    NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];
    NSLog(@"%@",dic);
    KTKBeacon *newBeacon = [[KTKBeacon alloc] initWithDictionary:dic];
    return newBeacon;
}
