paymentMethod.tokenize(verificationDetails) returns unknown error

I’m trying to implement web payment API with EMV 3D secure to my web store.
I’m not sure the reason, but paymentMethod.tokenize(verificationDetails) returns unknown error on sandbox environment.

The code is almost identical with sample code, like this,

	const verificationDetails = {
	amount: '10.00',
	billingContact: {
		givenName: 'John',
		familyName: 'Doe',
		email: '[email protected]',
		phone: '3214563987',
	},
	currencyCode: 'JPY',
	intent: 'CHARGE',
	customerInitiated: true,
	sellerKeyedIn: false
	};
	const tokenResult = await paymentMethod.tokenize(verificationDetails);
	if (tokenResult.status === 'OK') {
		return tokenResult.token;
	} else {
		let errorMessage = `Tokenization failed with status: ${tokenResult.status}`;
		if (tokenResult.errors) {
			errorMessage += ` and errors: ${JSON.stringify(
				tokenResult.errors
			)}`;
		}
		throw new Error(errorMessage);
	}

It works without 3D secure, means tokenize() works without argument.

Javascript console said,

Tokenization has faild.
An unknown error has occurred.

I used “SCA testing in the Web Payments SDK” values on the document, but I think this error is not related to the specific test value.

Visa 4800 0000 0000 0004 or Mastercard 5222 2200 0000 0005.

I’ve got same error, I mean it happened at the same line of square.js, line 5826.
just line number, I could not get the exact reason of error.

FYI, same code works at production environment.
