Download image using SDWebImage, error -999 (or) SDWebImageErrorDomain Code=0 "Downloaded image has 0 pixels

I am unable to download the image in Objective c Using SDWebImage 4.4.5 version., I tried the following , nothing worked.

Try 1:

[self.thumbnailImageView sd_setImageWithURL:[NSURL URLWithString:thumbnailURLString] completed:^(UIImage * _Nullable image, NSError * _Nullable error, SDImageCacheType cacheType, NSURL * _Nullable imageURL) {

}];

Try 2:

[self.thumbnailImageView sd_setImageWithURL:[NSURL URLWithString:thumbnailURLString] placeholderImage:nil options:SDWebImageRefreshCached completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) { if(image != nil){
            self.thumbnailImageView.image = image;                
        } else {
            NSLog(@"Photo Not Available, fetch");
            [self.thumbnailImageView sd_setImageWithURL:[NSURL URLWithString:thumbnailURLString] placeholderImage:nil options:SDWebImageRefreshCached completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
                if(image != nil) { NSLog(@"Lo Res Image Loaded by %ld from '%@'", (long)cacheType, imageURL);
                    self.thumbnailImageView.image = image;

                } else {
                    self.thumbnailImageView.image = nil;

                } }];

        } }];

Try 3:

[[SDWebImageDownloader sharedDownloader] downloadImageWithURL:[NSURL URLWithString:thumbnailURLString] options:SDWebImageDownloaderUseNSURLCache progress:nil completed:^(UIImage *image, NSData *data, NSError *error, BOOL finished) {


        }];

Try 4:

SDWebImageManager *manager = [SDWebImageManager sharedManager];

        [manager loadImageWithURL:[NSURL URLWithString:thumbnailURLString] options:SDWebImageDelayPlaceholder progress:^(NSInteger receivedSize, NSInteger expectedSize, NSURL * _Nullable targetURL) {
        } completed:^(UIImage * _Nullable image, NSData * _Nullable data, NSError * _Nullable error, SDImageCacheType cacheType, BOOL finished, NSURL * _Nullable imageURL) {

        }];

Try 5:

SDWebImageDownloader *manager = [SDWebImageManager sharedManager].imageDownloader;
        [manager setValue:@"application/vnd.learning.events.v1+json" forHTTPHeaderField:@"Accept"];
        [manager setValue:@"en-US" forHTTPHeaderField:@"Accept-Language"];
        [manager setValue:@"application/json; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
        //[manager setValue:savedEmail forHTTPHeaderField:@"Email"];
        [manager setValue:savedToken forHTTPHeaderField:@"Authorization"];
        [manager downloadImageWithURL:[NSURL URLWithString:thumbnailURLString] options:SDWebImageDownloaderHighPriority progress:^(NSInteger receivedSize, NSInteger expectedSize, NSURL * _Nullable targetURL) {
        } completed:^(UIImage * _Nullable image, NSData * _Nullable data, NSError * _Nullable error, BOOL finished) {
            self.thumbnailImageView.image = image;
        }];

In all the above cases, getting the following error:

Error Domain=NSURLErrorDomain Code=-999 "cancelled" UserInfo={NSErrorFailingURLStringKey=https://thisisnotcorrecturl.net/api/BAImage?ActionFlagId=97&id=615, NSErrorFailingURLKey=https://thisisnotcorrecturl.net/api/BAImage?ActionFlagId=97&id=615, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalDataTask <92586538-B07D-46FB-8694-3B29AA3F0CB4>.<7>" ), _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <92586538-B07D-46FB-8694-3B29AA3F0CB4>.<7>, NSLocalizedDescription=cancelled}

Earlier, we used v3.5.4 version used, able to download the image with the following code. It's working good.

[self.thumbnailImageView setImageWithURL:[NSURL URLWithString:thumbnailURLString]
                            placeholderImage:nil
                                   completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {
                                       if (image != nil){
                                           self.thumbnailImageView.image = [self imageResizingToAspetRatio:image];

                                       }
                                   }];

Kindly let me know if did any mistake, or any suggestions.

Update 1: Tried to download the image using post man. Kindly check the image. The same image URL is working on SDWebImage v3.5.4 after i upgraded to SDWebImage v4.4.5, it is not lodging the image.

Is there any configurations am i missing? Installed pod 'SDWebImage/WebP' also, added SD_WEBP=1 in Build settings -> Preprocessor macros.

Error: Error Domain=SDWebImageErrorDomain Code=0 "Downloaded image has 0 pixels" UserInfo={NSLocalizedDescription=Downloaded image has 0 pixels}

I faced the same issue and I was trying webP images. I realised later that I need to add webP coder to SDImageCodersManager. Something like 

SDImageCodersManager.shared.addCoder(SDImageWebPCoder.shared)

I did this in AppDelegate.

If you are suffering such type issue from SDWebImage library you can go with other one as well which are supporting base64 string object

One of best library I found is "Kingfisher"

Hope you like this and it will solve your issue.

Basically, SDWebImage has no issue for downloading them from any URL if the URL contains an image.

But in your case, you have tried to get an image from JSON. Your server API returns a JSON object that contains the image as base64String. When you get the JSON response then you need to get the base64String from json and then create an image from the base64String.

You can use this method for decoding string to image using Objective C.

- (UIImage *)decodeBase64ToImage:(NSString *)strEncodeData {
  NSData *data = [[NSData alloc]initWithBase64EncodedString:strEncodeData options:NSDataBase64DecodingIgnoreUnknownCharacters];
  return [UIImage imageWithData:data];
}

First, update pod and try SDWebImage pod version 3.8.2.

And the second thing is to check your image URL. because I personally test image download with this pod version and downloading functionality is working.
