meteor - Paypal muestra "No token passed" al hacer clic en el botón de PayPal

paypal-express

Question

Por alguna razón, el pago exprés de PayPal no funciona conmigo y me muestra una página vacía que dice:

Sin token pasado

Debajo está mi código para obtener la respuesta del servidor desde la URL, ya que el archivo que contiene el código es global, cualquier página puede usarse para procesar la respuesta correcta.

 setTimeout(function () {
var paypalToken = Router.current().params.query.token;
var paypalPayerId = Router.current().params.query.PayerID;
var price = '''';
var itemId = '''';
if (paypalToken != undefined && paypalPayerId != undefined) {
check(paypalToken, String);
check(paypalPayerId, String);
check(price, String);
check(itemId, String);
Meteor.call(''fetchItemId'', paypalToken, function (err, data) {
if (err) {
alert(err);
}
else {
itemId = data;
Meteor.call(''fetchPriceById'', itemId, function (err, data) {
if (err) {
alert(err);
}
else {
price = data.toString();
Meteor.call(''processPayment'', paypalToken, paypalPayerId, price, function (error, result) {
Meteor.call(''fetchLatestToken'', function (err, data) {
if (err) {
alert(err);
}
else {
//console.log(data.itemId);
pathPaypal = "https://domain/item/" + data.itemId;
window.location = pathPaypal;
}
});
});
}
});
}
});
}
}
