TypeError: Cannot set property 'rel' of null error

Perfect perfect perfect script. I love it!!! Except I get this error for some reason on mobile device and not sure how to fix?
If i resize the browser to a smaller size, all is fine. It only shows up when I select a device to test, or when I view on mobile. It leaves the entire screen blank.

Any ideas what could be happening?

Is there a way I can stop it detecting the device and just go by the CSS breakpoints?

Oh I figured it out minutes after posting! Ignore this, sorry!

I was missing the <link rel="preload" as="style" at the start of the stylesheet! Whoops!

Great script!!
