苹果内购获取商品问题

苹果内购获取商品问题。

已经通过如下代码获取ipaChannel

uni.getProvider({  
          service: 'payment',  
          success: (res) => {  
            iapChannel = res.providers.find((channel) => {  
              return (channel.id === 'appleiap')  
            })  
          }  
        });

打印ipaChannel显示

{  
    "id": "appleiap",  
    "description": "In-App Purchase",  
    "serviceReady": true,  
    "installService": "function() { [native code] }",  
    "appStoreReceipt": "function() { [native code] }",  
    "finishTransaction": "function() { [native code] }",  
    "restoreCompletedTransactions": "function() { [native code] }",  
    "restoreComplateRequest": "function() { [native code] }",  
    "requestProduct": "function() { [native code] }",  
    "requestOrder": "function() { [native code] }",  
    "isReadyToPay": "function() { [native code] }",  
    "isAppExist": true  
}

接下来尝试获取商品列表（vue3）
pointProducts.value可以确定是如下数据（和在苹果后台设置的商品ID一致）

[ "point_500", "point_1000", "point_2000" ]

之后尝试获取商品列表

channel.value.requestProduct(pointProducts.value, function (orderList) {  
            console.log('商品信息', orderList);  
        }, function (err) {  
            console.error('获取商品失败', err);  
        });

直接打印出来的是“获取商品失败”：

{  
    "code": -100,  
    "message": "Payment_appleiap:返回订单信息失败,https://ask.dcloud.net.cn/article/282",  
    "errCode": -100,  
    "errMsg": "Payment_appleiap:返回订单信息失败,https://ask.dcloud.net.cn/article/282"  
}  

想知道可能出错的原因在哪里，是自己的问题，还是苹果的问题。
多谢高人指点。
