Hello, I'm trying to create a custom visualization in Trackster. I am doing the following steps. Visualization -> New Visualization -> Add a Custom Build

I get directed to the url below:

http://galaxy.ca:8080/user/dbkeys?use_panels=True

But the web page says:

Server Error An error occurred. See the error logs for more information. (Turn debug on to display exception reports here)

My paster.log file shows the following:
