How to debug a page not rendering at all (and no errors being thrown)

Hi all,

I made mostly simplistic changes to a page, other than implementing a date picker function - on my local machine, all pages load fine, except this one page that includes these updates. When I open up the Chrome network console, I’m not thrown any errors at all - so I’m finding it difficult to figure out how to find what is going wrong, specifically.

Any ideas?

In fact this looks exclusively to do with the date picker, found this error on the console:

Uncaught TypeError: H is not a function
at new i (daterangepicker.min.js:7)
at HTMLInputElement. (daterangepicker.min.js:7)
at Function.each (jquery-3.3.1.slim.min.js:2)
at w.fn.init.each (jquery-3.3.1.slim.min.js:2)
at w.fn.init.R.fn.daterangepicker (daterangepicker.min.js:7)
at n.update (datePicker.js:169)
at n.render (datePicker.js:150)
at n.constructor (BaseComponent.js:20)
at n (appConnect.js:488)
at n.constructor (formElement.js:5)
