I’m attempting to build from the latest commit on git and receive the following
error upon attempting to access the application web ui:
HTTP ERROR: 500
Problem accessing /jobs/. Reason:
Server Error
Powered by Jetty://
My driver also prints this error:

Has the ui been disabled intentionally for development purposes, have I not set
something up correctly, or is this a bug?
