SetImageWithURLRequest: placeholderImage: success: failure Block not called

I am trying to get an image asynchronously with a url with AFNetworking 2.0

My problem is that neither success nor failure is named

I checked my url in browser so the problem is not here

UIImageView *imgv = [[UIImageView alloc] init];
[imgv setImageWithURLRequest:myURL
            placeholderImage:nil
                     success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) {
                                        /*some code*/
                     failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error) {
                                        /*some code*/       
];

      

        
        
        
      

    

When I look deeper inside setImageWithUrlRequest:placeholderImage:success:failure

   __weak __typeof(self)weakSelf = self;
    self.af_imageRequestOperation = [[AFHTTPRequestOperation alloc] initWithRequest:urlRequest];
    self.af_imageRequestOperation.responseSerializer = self.imageResponseSerializer;
    [self.af_imageRequestOperation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        __strong __typeof(weakSelf)strongSelf = weakSelf;
        if ([[urlRequest URL] isEqual:[strongSelf.af_imageRequestOperation.request URL]]) {
            if (success) {
                success(urlRequest, operation.response, responseObject);
            } else if (responseObject) {
                strongSelf.image = responseObject;
            }

            if (operation == strongSelf.af_imageRequestOperation){
                    strongSelf.af_imageRequestOperation = nil;
            }
        }

        [[[strongSelf class] sharedImageCache] cacheImage:responseObject forRequest:urlRequest];
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        __strong __typeof(weakSelf)strongSelf = weakSelf;
        if ([[urlRequest URL] isEqual:[strongSelf.af_imageRequestOperation.request URL]]) {
            if (failure) {
                failure(urlRequest, operation.response, error);
            }

            if (operation == strongSelf.af_imageRequestOperation){
                    strongSelf.af_imageRequestOperation = nil;
            }
        }
    }];

      

        
        
        
      

    

My code worked successfully [self.af_imageRequestOperation setCompletionBlockWithSuccess:^( AFHTTPRequestOperation *operation, id responseObject) {

, but I noticed that __strong __typeof(weakSelf)strongSelf = weakSelf;

bothnil

Any idea?
