Using Meteor.wrapAsync to wrap a callback inside a method - meteor

Question

This Meteor code is giving the error:
Error: Meteor code must always run within a Fiber. Try wrapping callbacks that you pass to non-Meteor libraries with Meteor.bindEnvironment.
I tried Meteor.bindEnvironment for no avail and want to try Meteor.wrapAsync. I could not figure it out from the docs. Could some one please help me with the syntax? thx
Meteor.methods({
'createTransaction':
function (nonceFromTheClient, Payment) {
let user = Meteor.user();
gateway.transaction.sale(
{
arg_object
},
function (err, success) {
if (!err) {
//do stuff here
}
}
);
}
});

Wrap in Meteor.wrapAsync
Meteor.methods({
'createTransaction':
function (nonceFromTheClient, Payment) {
this.unblock();
let user = Meteor.user();
var sale = Meteor.wrapAsync(gateway.transaction.sale);
var res = sale({arg_object});
future.return(res);
return future.wait();
}
});
Or try wrapping it in Fiber
var Fiber = Npm.require('fibers');
Meteor.methods({
'createTransaction': function (nonceFromTheClient, Payment) {
Fiber(function() {
let user = Meteor.user();
gateway.transaction.sale(
{
arg_object
},
function (err, success) {
if (!err) {
//do stuff here
}
}
);
}).run()
}
});
Update: Here's how I handle stripe with Async.runSync and Meteor.bindEnvironment
var stripe = require("stripe")(Meteor.settings.private.StripeKeys.secretKey);
Meteor.methods({
'stripeToken': function() {
this.unblock();
var future = new Future();
var encrypted = CryptoJS.AES.encrypt(Meteor.userId(), userIdEncryptionToken);
future.return(encrypted.toString());
return future.wait();
},
'stripePayment': function(token) {
var userId = Meteor.userId();
var totalPrice = 0;
//calculate total price from collection
totalPrice = Math.ceil(totalPrice * 100) / 100;
userEmail = Meteor.users.findOne({
'_id': userId
}).emails[0].address;
// Create a charge: this will charge the user's card
var now = new Date();
Async.runSync(function(done) {
var charge = stripe.charges.create({
amount: Math.ceil(totalPrice * 100), // Amount in cents // coverting dollars to cents
currency: "usd",
source: token,
receipt_email: userEmail,
description: "Charging"
}, Meteor.bindEnvironment(function(err, charge) {
if (err) {
//handle errors with a switch case for different errors
done();
} else {
//handle res, update order
}
}));
}); // Async.runSync
},
});
