JS Errors while loading

Hello,
I just noticed today that not all thumbnails are loading. It happens on every page that had the gallery. In console i noticed js error.

Uncaught TypeError: b.loadIMG(...).then(...).catch is not a function
    at Object.<anonymous> (foogallery.min.js?ver=2.0.35:11)
    at Function.Deferred (vendor.js?v4&ver=5.7.2:9)
    at f.load (foogallery.min.js?ver=2.0.35:11)
    at foogallery.min.js?ver=2.0.35:11
    at Array.forEach (<anonymous>)
    at IntersectionObserver.<anonymous> (foogallery.min.js?ver=2.0.35:11)
