“Uncaught TypeError: Cannot read property ‘getAttribute’ of undefined”

There are some posts about this error for Drupal 7, but I’m using Drupal 8.1 and those solutions don’t work for D8.

I tried this patch (coded for D7) and doesn’t work.

The effect of the error is that QuickEdit doesn’t work: sometimes the quick edit link doesn’t appears, sometimes it appears but when edit some fields I get error.

Can anybody help?

UPDATE for neograph: I haven’t changed anything about the loading of the javascript. The only thing I did is edit the my_theme.libraries.yml for adding JS plugins:

global-css:   css:     theme:       #css/style.css: { }       dist/css/style.css: { }  global-js:   js:     #js/script.js: { }     bower_components/slick-carousel/slick/slick.min.js: { }     bower_components/slicknav/dist/jquery.slicknav.min.js: { }     bower_components/superfish/dist/js/superfish.min.js: { }     dist/js/script.js: { }   dependencies:     - core/jquery
