Error when the wrapper vast response is empty

Question

Hi,
When the targeted adserver returns an empty vast response through the Wrapper/VASTAdTagURI tag, the error below is triggered :
TypeError: Error #1010: A term is undefined and has no properties.

to prevent the error, use:
if(_LinearAdsArray.length!=0){
return _LinearAdsArray[0].videoDuration;
