This is looking good. Thanks for attaching the screenshot. However, I
wonder if there's a better way to present it from a UI perspective. Right now
when you get a failure the table kinda crams all the other columns to make
space for this ugly (but helpful) message. This is an existing problem in the
stages page, when one of the tasks fails the task table does the same. Not a
big deal, but maybe we should do a front-end fix for it at some point. I think
the right way to go is to add some JavaScript to make the exception expandable
on click (which doesn't have to be part of this PR).
