Address can't be loaded

Error message

Address can't be loaded

What it means

Thrown in EditAddressAsync when GetCustomerAddressAsync(customer.Id, addressModel.Id) returns null — i.e., the address id in the edit form does not belong to the current customer (or no longer exists). The null-coalescing throw produces Exception("Address can't be loaded"), caught at line 304 and returned as JSON. It guards against a customer editing an address id they do not own.

Solutions

1. Refresh the address list and edit a currently-valid address id.
2. Ensure the address was not deleted in another session/tab before submitting.
3. Return a clear 'address no longer available' JSON and let the customer re-select.
4. Validate addressModel.Id belongs to the customer before opening the editor.

Example fix

// before
var address = await _customerService.GetCustomerAddressAsync(customer.Id, addressModel.Id)
    ?? throw new Exception("Address can't be loaded");
// after (localized message)
var address = await _customerService.GetCustomerAddressAsync(customer.Id, addressModel.Id);
if (address is null)
    throw new Exception(await _localizationService.GetResourceAsync("Checkout.AddressNotFound"));

// Confirm the address belongs to the customer before editing.
var address = await _customerService.GetCustomerAddressAsync(customer.Id, addressModel.Id);
if (address is null)
    return Json(new { error = 1, message = "Address is no longer available." });

static bool AddressOwned(Address a) => a is not null;

// Wrapped by EditAddressAsync catch returning JSON error.
catch (Exception exc) { return Json(new { error = 1, message = exc.Message }); }

When it happens

Trigger: The posted addressModel.Id has no matching row in the customer's address book (CustomerAddress mapping). Triggered by a stale address id, an address deleted in another tab, a tampered form, or a guest-to-registered conversion where address book ids changed.

Common situations: Address deleted by the customer/admin between page load and edit submit; multi-tab checkout where one tab removes the address; form tampering to access another customer's address id; address book rebuilt after account merge leaving old ids invalid.
