mtc.js reporting errors

Hi
I’m getting starting 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
