JSONModel Invalid JSON data

I have this Json out of ASP MVC API I have the InvModel and the LotModel

but when I call

_InvFeed = [[InvModel alloc] initFromURLWithString:@"http://192.168.1.206/service/api/dto/inventory/1?p=Red%20Globe"
                                        completion:^(JSONModel *model, JSONModelError *err) 
        {
            NSLog(@"Inventory: %@", _InvFeed );
            NSLog(@"Error: %@",err);
        }];

I can not figure out this error:

Error: Error Domain=JSONModelErrorDomain Code=1 "Invalid JSON data: Attempt to initialize JSONModel object using initWithDictionary:error: but the dictionary parameter was not an 'NSDictionary'."
UserInfo=0x109075ff0 {NSLocalizedDescription=Invalid JSON data: Attempt to initialize JSONModel object using initWithDictionary:error: but the dictionary parameter was not an 'NSDictionary'., kJSONModelKeyPath=LotDTO}

JSONData

and here are the JSONModels for: LotDTO

#import "JSONModel.h"

@interface InvLotModel : JSONModel
@property (assign, nonatomic) int lotid;
@property (strong, nonatomic) NSDate* expdate;
@property (strong, nonatomic) NSString* lotserial;
@property (strong, nonatomic) NSDate* lastupddate;
@property (strong, nonatomic) NSString<Optional>* providerlotserial;
@property (assign, nonatomic) NSDecimal* qtyoriginal;
@property (assign, nonatomic) NSDecimal* qtyallocated;
@property (assign, nonatomic) NSDecimal* qtyavailable;
@property (assign, nonatomic) NSDecimal* qtyonhand;
@property (strong, nonatomic) NSDate* receiptdate;
@property (strong, nonatomic) NSString* linecomment;
@property (assign, nonatomic) NSDecimal* unitcost;
@property (strong, nonatomic) NSString* warehouse;
@end

And here the Inventory Model

#import "JSONModel.h"
#import "InvLotModel.h"
@protocol InvModel @end
@interface InvModel : JSONModel
@property (assign, nonatomic) int id;
@property (strong, nonatomic) NSString* itemid;
@property (strong, nonatomic) NSString* description;
@property (strong, nonatomic) NSDate* createdate;
@property (strong, nonatomic) NSString* createuser;
@property (assign, nonatomic) float lastcost;
@property (assign, nonatomic) BOOL monitorlevel;
@property (assign, nonatomic) int minlevel;
@property (assign, nonatomic) int maxlevel;
@property (strong, nonatomic) NSString* gtin;
@property (assign, nonatomic) float weight;
@property (strong, nonatomic) NSString* uom;
@property (strong, nonatomic) NSString* sizes;
@property (strong, nonatomic) NSString* variety;
@property (strong, nonatomic) NSString <Optional>* bag;
@property (strong, nonatomic) NSString* style;
@property (strong, nonatomic) NSString* box;
@property (strong, nonatomic) NSString* label;
@property (strong, nonatomic) NSString* commodity;

@property (strong, nonatomic) InvLotModel* LotDTO;
@end

Please replace this

@property (strong, nonatomic) InvLotModel* LotDTO;

with this

@property (strong, nonatomic) NSArray<InvLotModel,ConvertOnDemand>* LotDTO;

As officials at JSONModel suggest to use ConvertOnDemand to convert NSArray to JSONModelArray in one of their tutorial to avoid error in implenentation.

Make sure to mark any extension property as Ignore. I faced such an issue trying to copy the model.

I see two problems:

1) In the InvModel class, yo have defined LotDTO as a single object, not an array.

2) In the JSON response you have posted, the syntax for LotDTO does not seem to me valid JSON. It appears to be an array of LotDTO objects, but it does not follow the syntax for JSON arrays (which you can check, for example, here).
