Javascript createOrder后的Paypal签出重定向URL

我尝试在Javascript中使用新的paypal方法作为结帐按钮，但一旦付款完成，我就无法重定向用户

这是我的密码：

    paypal.Buttons({
        // Set up the transaction
        createOrder: function(data, actions) {
            return actions.order.create({
                application_context: {
                    return_url: 'https://url.com/ok.php',
                    cancel_url: 'https://url.com/nok.php',
                    brand_name: "AKAZ",
                    locale: "fr-FR",
                    user_action: "CONTINUE"
                },
                purchase_units: [{
                    amount: {
                        value: '175.20'
                    }
                }]
            });
        },
        onApprove: function(data, actions) {
            return actions.payment.execute().then(function() {
                    actions.redirect();
                }
            );
        },
        onCancel: function (data, action) {
            return actions.payment.execute().then(function() {
                    actions.redirect();
                }
            );
        }
    }).render('#paypal-button-container');

并读取paypal文档

未捕获错误：预期返回url为空或。智能支付按钮集成禁止返回url。在
