Node-Red on Bluemix: Installing node-red-contrib-cep

I am new to both Node-Red as well as Bluemix. I have created a Node-Red running on Bluemix using the Bluemix IoT Platform starter kit.

I have tried to install node-red-contrib-cep using the Manage Palette -> Install but the installation failed with "Failed to install: node-red-contrib-cep Error: Install failed Check the log for more information"

How should I proceed from here?
