I just ran into something similar. I think the fact that you are Asserting from within the PoseContext causes this. The Assert throws and exception, and that's how exceptions are displayed.

I met the same error. It seems can not use the Assert and exception inside the PoseContext. I don't know whether there has a way to fix it.

I think the issue happens when we invoke var result = test.YearBeforeNow(); Is there any update on this issue?
