Apple Pay as an Adyen Web Component errors

Right now, I own an online business that accepts Apple Pay as an Adyen Web Component as a basketpage of my e-commerce platform. I validate names, addresses, and other personal details of each buyer to be sure everything will go smoothly. When I am trying to check out addresses, I only get a portion of info, not the full deal. Here are details of the error:
newTotal: {
label: this.client.getMerchantName(),
type: ‘final’,
errors: [
new ApplePayError(
‘International shipping is not available’
What might be causing it?
