Apple Pay Sandbox with Payment Not Completed

Team,

When I try using Apple pay for Japan, we are getting Payment Not Completed error for a merchant with Japanese character as the displayName at completeMerchantValidation.

The same works well if the merchant has name in English.

log from com.apple.passkit as explained in Apple Pay on the Web Debugging Guide

As we can see, com.apple.PassKit.PaymentAuthorizationUIExtension: (PassKitMacHelper) [com.apple.passkit:PaymentUI] Payment failed with fatal error <private>, how do we debug this further?

I read the document again,

A string of 64 or fewer UTF-8 characters containing the canonical name for your store, suitable for display. This needs to remain a consistent value for the store and shouldn’t contain dynamic values such as incrementing order numbers. Don’t localize the name. Use only characters from the supported character sets in the fonts listed in the table below.

ref : Request Parameters

how we are invoking the completeMerchantValidation()

    session.completeMerchantValidation({
      displayName: 'じゃ', //utf-8 string
      //... other params from the docs
    })

Can you please help to understand if it adheres to use canonical name. don't localize..
Note: if the displayName is in english, it works.
