Migrated Xibo Install - Cannot schedule displays - Unexpected Error

Good afternoon,

I just finished setting up a new Xibo install (2.0, docker, no changes to the standard image).
I moved my data over from my old Windows server (1.7.X) install, and got it to convert correctly. However, when I go to schedule a display, I get an “Unexpected Error, Please contact support” message.
Any suggestions/ideas on where to look?
