You should use version 2.0.alpha of PennController. I was assuming that you were using the (new) PCIbex Farm, where PennController 2.0.alpha comes with new projects by default. You will need to download the file PennController.js from the linked github page and upload it to your project—note that if you previously git-synced PennController.js, you might not be able to overwrite it, unless you git-sync it again from elsewhere (for example, you could create a git repo for your project)
Right now your experiment seems to be using version 1.8-dev, and I don’t see the error message that you report. Were you able to make things work in the end?
