3d object - Mirror in threeJS

I am working on 3d product demo, where i need to show the product reflection/ mirror. I have tried the example - http://ift.tt/29DJyQj. i made a replica of the example before actually implementing it with my project. When publish it to web, nothing is displayed on the screen and in the inspect you can see the error message "TypeError: this.renderTarget.texture is undefined" in mirror.js. How to resolve it. Thanks
