贝宝-多笔交易退款-节点js-异步问题

Question

我在我的React应用程序中使用PayPal付款，在这里我试图为选择退出比赛的用户退款。我曾经在后端节点js上执行退款。

好，开始讨论这个问题。当我要进行多次退款时，我将无法执行退款。 以下是我用于对多笔交易进行退款的代码。这是我使用的SDK https://github.com/paypal/Checkout-NodeJS-SDK。

对于异步，我已经推荐了此博客https://zellwk.com/blog/async-await-in-loops/

我在日志中没有错误。

app.post('/tournament/users/withdraw',VerifyRoute,(request, response)=>{
    const {withDrawUsers,tournament_id,registration_fee,payer_info}=request.body;
    ....
    ....
    to_withdraw.map(async(withDrawUsers)=>{
            function client() {
                let clientId = "xyz";
                let clientSecret = "abc";
                let environment = new checkoutNodeJssdk.core.SandboxEnvironment(clientId, clientSecret);
                return  new checkoutNodeJssdk.core.PayPalHttpClient(environment);
            }
            async function refundOrder(captureId,amount ,debug=false) {
                try {
                    const request = new checkoutNodeJssdk.payments.CapturesRefundRequest(captureId);
                    request.requestBody({
                            "amount": {
                            "value": amount,
                            "currency_code": "USD"
                            }
                    });
                    const response = await client().execute(request);
                }
                catch (error) {
                    errorLogger.error("Error refunding the order "+error);
                }
            }   
                (async() => await refundOrder(withDrawUsers.transaction_id,(registration_fee*(withDrawUsers.noOfUsers)).toString(),false))();
        })
    });   
});
