Getting error "Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: bad request (400)" in iOS 7

Question

I am using AFNetworking version "2.5.4" and creating multipartform-data request. In my case code is working fine on iOS8 but issue on iOS 7. Getting Error

"Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: bad request (400)"

UserInfo=0x19039c00 {com.alamofire.serialization.response.error.response= { URL: http://xxx/api/abc/PostApi } { status code: 400, headers { Connection = close; "Content-Type" = "application/json"; Date = "Wed, 20 May 2015 05:42:47 GMT"; Server = Apache; } }, NSErrorFailingURLKey=http://xxx/api/abc/PostApi }, NSLocalizedDescription=Request failed: bad request (400), com.alamofire.serialization.response.error.data=<7b227375 63636573 73223a66 616c7365 2c226d65 73736167 65223a22 4e6f2064 61746122 2c226461 7461223a 5b5d2c22 72657370 6f6e7365 5f636f64 65223a22 52433030 3033227d>}

This is my Code that have issue

`

@property (strong, nonatomic) NSURLSessionUploadTask *postUploadTask;

__block int i=1;
            AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

    NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:urlString parameters:postParameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        if (imageArray.count > 0) {
            long dataLenght = 0.0;
            for(UIImage *eachImage in imageArray)
            {
                NSData *imageData = UIImageJPEGRepresentation(eachImage, .5);
                dataLenght = dataLenght + imageData.length;
                [formData appendPartWithFileData:imageData name:[NSString stringWithFormat:@"image%d",i] fileName:[NSString stringWithFormat:@"image%d.jpg",i] mimeType:@"image/jpeg"];
                i++;
            }

        }
    } error:nil];

    NSProgress *progress = nil;
    self.postUploadTask = [manager uploadTaskWithStreamedRequest:request progress:&progress completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
        [progress removeObserver:object forKeyPath:kProgressFractionCompleted context:kPostUpdateTypePostUpdate];
        completionBlock(responseObject, error, task);
    }];
    [self.postUploadTask resume];` 

While this is working code on same api-:

     AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:BASE_URL]];

    AFHTTPRequestOperation *op = [manager POST:urlString parameters:postParameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        if (imageArray.count > 0) {
            long dataLenght = 0.0;
            for(UIImage *eachImage in imageArray)
            {
                NSData *imageData = UIImageJPEGRepresentation(eachImage, .5);
                dataLenght = dataLenght + imageData.length;
                [formData appendPartWithFileData:imageData name:[NSString stringWithFormat:@"image%d",i] fileName:[NSString stringWithFormat:@"image%d.jpg",i] mimeType:@"image/jpeg"];
                i++;
            }
        }
    } success:^(AFHTTPRequestOperation *operation, id responseObject){

        completionBlock(responseObject, nil, task);

        [progress removeObserver:object forKeyPath:kProgressFractionCompleted context:kPostUpdateTypePostUpdate];

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        completionBlock(operation, error, task);

    }];
    [op start];

But My requirement is to implement uploadTaskWithStreamedRequest. This is similar to issue"Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: bad request (400)".

Please help me guys if have any idea about it. Thanks in advance.

You should try adding request serializer to your AFHTTPRequestOperationManager.

    AFJSONRequestSerializer *jsonRequestSerializer = [AFJSONRequestSerializer serializer];
    [self.requestOperationManager setRequestSerializer:jsonRequestSerializer];
