Hello Megan,
Are you still seeing this error? I did some research in our Support console and it looks like a few other customers have run across a similar issue. What you'll need to do is create a support ticket at support.apptio.com. Then our support team can triage it and work on getting it resolved as quickly as possible.
Kind regards,
Debbie Hagen
