Unhelpful error message when Jinja key doesn't exist

I came across this error when running some release workflows. The cause of this was that our build infrastructure is currently running an older version of StackStorm (which will very soon be remedied via the new ops work), so the st2kv implemented in https://github.com/StackStorm/st2cd/pull/266 was not a thing. However, this error message didn't help me in any way to come to this conclusion - would be nice to see something different here.
