Intermittent errors when calling an event

Hello,

I have a coldbox application in which I am rendering several UI components, each based data from their respective coldbox events.
One of the events intermittently returns error messages that are inconsistent.
For example sometimes “[EventName] is not valid registered event.” will be returned, sometimes it will be “[random property] is undefined”
and sometimes it will render correctly with the same code being executed each time on the same machine of course.

Has anyone seen a similar issue or know why such errors might occur?

Here is a sampling of the error messages, edited to replace object names:
