I hadn’t expected to have to debug this! 🙂

I ran a little test and inserted the following code ahead of line 1272 in the code:
$WC = WC();
$countries = $WC->countries;
$shipping_countries = $countries->get_shipping_countries();

The error occurred on the third line, which suggests that WC()->countries hadn’t been initialised when this code was called.

This works

$WC_Countries = new WC_Countries();
// Get the country list from Woo....
foreach ($WC_Countries->get_shipping_countries() as $id => $value) :
   $this->country_array[esc_attr($id)] = esc_js($value);
endforeach;

FYI I’m on the latest version of Woocommerce 7.9.0 and the shipping country restrictions are left as default (i.e.’all’)
