Here is the error I am returned:

VERSION: '52.0',
BUILD: '22708556'
L_ERRORCODE0: '10410',
L_SHORTMESSAGE0: 'Invalid token',
L_LONGMESSAGE0: 'Invalid token.',
L_SEVERITYCODE0: 'Error'
Client side:
<form id="myContainer" method="post" action="/api/payment/payone"></form>
<script>
window.paypalCheckoutReady = function () {
paypal.checkout.setup('XXX', {
environment: 'sandbox',
container: 'myContainer'
});
};
</script>
<script src="//www.paypalobjects.com/api/checkout.js" async></script>
API:
payone: function(req, res) {
var paypal = require('paypal-express-checkout').init('username', 'password', 'signature', 'return url', 'cancel url', 'debug');
paypal.pay('20130001', 10.00, 'XX', 'USD', false, function(err, url) {
if (err) {
console.log(err);
return;
}
res.redirect(url);
});
paypal.detail( "token", "PayerID", function(err, data, invoiceNumber, price) {

return;

Usually we encounter Error 10410 if there is incorrect token or no token passed.
please make sure that you are passing the right PayPal Express token.
