Error while uploading images to SAP Mobile Documents from iPad application using ObjectiveCMIS.

Question

Hi,
I am getting the error while uploading images to SAP Mobile Documents from custom iOS(iPad )application using ObjectiveCMIS library.
My Custom method is as follows:
- (void)createSalesOrderRouteMapImageInFolder:(NSString*)salesOrderRouteMapFolderId routeMapImageTitle:(NSString *)imageTitle routeMapContent:(NSData *)imageData
    NSInputStream *inputStream = [NSInputStream inputStreamWithData:imageData];
    NSMutableDictionary *properties = [NSMutableDictionary dictionary];
    [properties setObject:[NSString stringByAppendingFileExtension:imageTitle] forKey:@"cmis:name"];
    [properties setObject:@"cmis:document" forKey:@"cmis:objectTypeId"];
    [self.session createDocumentFromInputStream:inputStream
                                       mimeType:@"image/png"
                                     properties:properties
                                       inFolder:salesOrderRouteMapFolderId
                                  bytesExpected:[imageData length]
                                completionBlock:^(NSString *objectId, NSError *error) {
                                    NSLog(@"Object id is %@",objectId);
                                    if(error == nil) {
                                        [inputStream close];
                                        NSLog(@"Uploading Sales order route map successfully.");
                                        [[NSNotificationCenter defaultCenter] postNotificationName:SaveOrderSuccessNotification object:nil];
                                    } else {
                                        [inputStream close];
                                        NSLog(@"Uploading sales order route map failed.");
                                        [[NSNotificationCenter defaultCenter] postNotificationName:SaveOrderFailedNotification object:error];
                                } progressBlock:^(unsigned long long bytesUploaded, unsigned long long bytesTotal) {
                                    NSLog(@"uploading... (%llu/%llu)", bytesUploaded, bytesTotal);
