Using external javascript library gives errors in AMT

Trying to use javascript libraries like video.js and video_markers.js with jquery to show markers on given time in the video slider of the video. But after adding the library, AMT gives below error. I am not using any select elements in the crowd form myself, looks like this is for the javascript library added , how can I resolve it, can someone please advise?. Thanks
