안녕하세요. 잘 동작하던 결제창이 다음과 같은 에러가 발생하면서 결제창이 뜨지 않네요. @Tosspayments/payment-sdk 1.6.5 사용중이며, PC 환경의 크롬브라우져입니다.

  
async function requestPayment() {
    const tossPayments = await loadTossPayments(clientKey);

    if (orderDetail) {
      tossPayments.requestPayment("카드", {
        amount: orderDetail.result.price,
        orderId: orderDetail.result.orderId,
        orderName: orderDetail.result.orderName,
        customerName: orderDetail.result.customerName,
        successUrl: `${window.location.origin}/payment/success`,
        failUrl: `${window.location.origin}/payment/fail`,
      });
    }
  }

  
async function requestPayment() {
    const tossPayments = await loadTossPayments(clientKey);

    if (orderDetail) {
      tossPayments.requestPayment("카드", {
        amount: orderDetail.result.price,
        orderId: orderDetail.result.orderId,
        orderName: orderDetail.result.orderName,
        customerName: orderDetail.result.customerName,
        successUrl: `${window.location.origin}/payment/success`,
        failUrl: `${window.location.origin}/payment/fail`,
      });
    }
  }
