Eror in plugin js

Hi
I have this error in my site:

Uncaught TypeError: jQuery(...).perfectScrollbar is not a function
    at woofc_perfect_scrollbar (frontend.js?ver=5.0.7:349:9)
    at woofc_cart_loaded (frontend.js?ver=5.0.7:342:3)

    at s.fn.init.trigger (jquery.min.js?ver=3.6.0:2:72086)

How can I fix this? There is no such error on another site
Thank you!
