* @return KalturaFlavorAsset The exported asset

Since KalturaCaptionAsset is not an inheritor of KalturaFlavorAsset but of KalturaAsset - this return type causes generated client libraries to throw an error on the return type. It's not a major issue since the export still takes place, but still worth fixing.
