I got this error Uncaught TypeError: Cannot read property 'autocomplete' of undefined.

So I checked the file in /pub/static/frontend/Sm/himarket/nl_NL/Magento_Customer/js/view/authentication-popup.js and did not find a thing.

Does someone has an idea? It says line 26: autocomplete: window.checkout.autocomplete,

I don't have an checkout window.
