Problems with: address-i18n.min.js

Just to add, I’ve found the source for this error.

It’s due to a function removing the “state” adress field.

// Hook in
add_filter( 'woocommerce_default_address_fields' , 'custom_override_checkout_fields' );

// Our hooked in function - $fields is passed via the filter!
function custom_override_checkout_fields( $fields ) {
     unset($fields['state']);

     return $fields;
}

The thing is the code works, but I get a JS error. Is there any workaround, because asking for the state / kanton in Switzerland doesn’t really make any sense.

Thanks!
