PayPal Vault集成问题：createVaultSetupToken回调提示无客户ID

我正在结账支付信息区域开发功能，让客户输入银行卡信息，以便出现市场损失时通过PayPal后续扣费。使用PayPal SDK实现卡片保存及扣费功能时，在createVaultSetupToken回调环节遇阻。

已实现的前后端逻辑 #

前端调用后端接口创建setup token并请求PayPal API，后端按文档传入空card对象的payment_source：

createVaultSetupToken: async (data) => {
     const result = await fetch("/PayPalExtended/setup/token", { method: "POST" })
              var jsonRes = await result.json()
              const { id } = jsonRes;
              return id;
},

请求返回201 Created并成功获取token，但PayPal SDK未触发OnApprove回调，反而抛出以下错误：

测试信息 #

• 使用的高级结账测试卡：

Number: 2223000048400011
date: 11/25
CCV:123
Name:  Mark Thomas

• 后端API返回结果：

{
  "jsonRes ": {
    "id": "2DV308********",
    "payment_source": {
      "Card": null,
      "Token": null
    },
    "customer": {
      "id": "uCEH******"
    },
    "status": "CREATED"
  }
}

• 引入的PayPal脚本地址：

https://www.paypal.com/sdk/js?client-id=clientId&currency=USD&intent=authorize&commit=false&vault=true&debug=false&components=buttons,card-fields" data-partner-attribution-id="NopCommerce_PPCP" data-page-type="checkout" data-user-id-token="data-user-id"

已尝试的解决方案 #

• 硬编码卡片信息
• 添加账单地址
• 更换测试卡
• 修改脚本参数

以上尝试均未解决问题。

*注：因采用电汇支付，可能出现失败或客户取消交易，需从客户卡中扣除损失金额。
