Hi Aaron,
Did you get this error in the import screen when you tried to import a file? I think it is referring Paxata connector process which runs independently of Paxata core server( @apatil - please let me know your thoughts).
If possible, please email the frontend.log and sysout.log files from Paxata core server to servicedesk@paxata.com
With Best Regards
