Node.js, Expressjs, Mongo, Jade: `new` action passing initialized mongo instance resulting in 'ReferenceError: jade is not defined'

Source: github

In trying to pass a freshly instantiated mongoose.model through expressjs' render function, I come upon the following error: "ReferenceError: jade is not defined"

The controller...

var mongoose = require("mongoose")
  , Client = mongoose.model("Client")

exports.new = function (req, res) {
    res.render("clients/new", {
        headline: "New Client",
        client: new Client({})
    })
}

I have also tried client: new Client(), storing the instantiated object in a var then passing it to the final render object with no change. Removing the new Client({}) bit gets past the 500 error, but does not solve the issue at hand.

Some config...

app.set("views", __dirname + "/app/views")
app.set("view engine", "jade")

The model...

var mongoose = require("mongoose")
  , Schema = mongoose.Schema

var Client = new Schema({
    company: { type: String },
    contact: {
        name: { type: String },
        phone: { type: String },
        email: { type: String }
    },
    created: { type: Date, default: Date.now }
})

mongoose.model("Client", Client)
