Twenty One Child Theme script.js error

[Jon87]

Hi Guys,

I have updated to 8.1 and decided to move over to Twenty One theme. I've created a child theme for my front end templates, and almost everything works perfectly.

The one problem I'm having is that script.js/script.min.js throw out a load of errors that seem to be preventing jquery from executing at all. I've checked and it only happens within the child theme. I have tried copying just the JS files across, and even tried copying across every theme file besides the template files I have edited but to no avail.

The errors given are;

main.js:501 Uncaught TypeError: Cannot read property 'addEventListener' of null
at main.js:501
scripts.js?v=eafa76:21193 Uncaught TypeError: Cannot set property 'setInputError' of undefined
at HTMLDocument.<anonymous> (scripts.js?v=eafa76:21193)
at fire (scripts.js?v=eafa76:3232)
at Object.fireWith [as resolveWith] (scripts.js?v=eafa76:3362)
at Function.ready (scripts.js?v=eafa76:3582)
at HTMLDocument.completed (scripts.js?v=eafa76:3617)

A page that they can be found on for example is;

Any suggestions you may have would be greatly appreciated.

Kind Regards,

Jon
