Meteor error on fast-rendering path TypeError: dynamics.slice is not a function

I receive the following error every time a page renders. I didn't receive these before, they just started one day and the only solution I found until now is to uninstall fast-render. Changing the routes in any way doesn't seem to have any effect. Any idea what the source of the problem could be?

Error

I found the following page which describes a similar error, but I don't have this.redirect(...) or Router.go(...) in a waitOn function: https://github.com/kadirahq/fast-render#3-waiton-and-subscriptions-methods

Here is the code for the Account Route and the corresponding controller:

Router.route("/account", {
    name: "Account",
    controller: simpleWebsiteController,
    waitOn: function () {
        return [
            Meteor.subscribe("userData"),
            Meteor.subscribe("userMessages")
        ]
    },
    data: function () {
        var messages = Collections.Messages.find({userId: Meteor.userId()},{sort: { creationDate: -1 }});
        var posts = Collections.Posts.find({});
        var comments = Collections.Comments.find({});
        return {
            content: "page-account",
            userMessages: messages,
            userComments: comments,
            userPosts: posts
        };
    },
    onBeforeAction: function () {
        // If the user is not logged in, redirect to login page
        var path = this.location.get().path;
        if (!Meteor.userId() && path.indexOf("/login") != 0)
            this.location.go("/login");
        else
            this.next();
    }
});

Controller:

var simpleWebsiteController = RouteController.extend({
    layoutTemplate: "MainLayout",
    waitOn: function () {
        return [
            Meteor.subscribe("userData"),
            Meteor.subscribe("categoriesList"),
            Meteor.subscribe("cityData")
        ]
    },
    onBeforeAction: function () {
        // If the user is not logged in, redirect to login page
        var path = this.location.get().path;
        if (!Meteor.userId() && path.indexOf("/login") != 0)
            this.location.go("/login");
        else
            this.next();
    },
    onAfterAction: function() {
      $('.row-offcanvas').removeClass('active');
      $('.collapse').removeClass('active');
    },
    fastRender: true
});

Check this answer for more information about the reason of this error.

Unfortunately the fast-render package that flow-router has as a dependency is messing around with meteor internals and would break your code as meteor's core code gets updated.

You can clone and edit kadira's fast-render and fix this problem.

Go to packages folder under your project's directory

cd your_project_dir/packages/

git clone https://github.com/kadirahq/fast-render.git

Then, edit your_project_dir/packages/fast-render/lib/server/context.js like so on line 23:

// support for Meteor.user
// Fibers.current._meteor_dynamics = {};
Fibers.current._meteor_dynamics = []; // <-- Fixed

Now this will overwrite kadira's v2.16.0 fast-render package.

this package update was the guilty in my case:

[email protected] -> [email protected]

Edit packages and/or versions files and should be ok.
