How to reprodeuce:
yarn run build
I think the error exists in theme-chalk/src/input.scss
SCSS varaibles in calc() function shoud be inside "#{}"
$input-padding-size-with-extra-icon: calc(
5px + map.get($input-font-size, $size) + map.get($input-padding-horizontal, $size)
);
This should be
$input-padding-size-with-extra-icon: calc(
5px + #{map.get($input-font-size, $size)} + #{map.get(
$input-padding-horizontal,
$size
)}
);
