This error became evident upon login into character.

I am running all of the latest files found here in GitHub

just in case more info is needed here is the rest of the fail code:

Do you currently have the reputation bar docklet active? if so what faction? or do you maybe have a 'blank' docklet slot that may be a bugging rep slot?
