我正在尝试将 Google-Tez 付款集成到我的网站中，但是当我调用 request.show() 时收到错误消息

“收款人不是有效的商家”

，当我调用 checkCanMakePayment() 得到错误消息时

“无法查询付款请求”

我在下面附上了我的代码。我的 UPI ID 是“ hsbc ”。谁能帮我解决这个问题？我需要知道是否有任何流程，例如商家必须向 Google Tez 注册

    function onBuyClicked() {

        const creditCardPaymentMethod = {
            supportedMethods: 'basic-card',
            data: {
                supportedNetworks: ['visa', 'mastercard'],
                supportedTypes: ['credit', 'debit']
            }
        };
        const supportedInstruments = [   
            {     
                supportedMethods: ['https://tez.google.com/pay'],

当您在“pa”字段中使用客户 VPA 代替商家 VPA 时，会出现“收款人不是有效的商家”错误。

解决方法：使用为商户签发的 VPA。
