mtc.js reporting errors

I’m getting started with mauting and just put the tracking js code in one page of my web site.

But the injected mtc.js is throwing one exception uncaught exception:

mtc.js:60 Uncaught TypeError: Cannot read property 'type' of undefined
    at mtc.js:60
    at mtc.js:3
    at Object.MauticJS.processGatedVideos (mtc.js:60)
    at MauticJS.initGatedVideo (mtc.js:59)

I really appreciate any information that could help me to fix this issue.

Thank you very much
