Taking this out of draft state to see if it helps CI pass. If it does (or at least if it gets far enough) I'll spin up an ephemeral to make sure it works as expected :)

/testenv up

@rusackas Ephemeral environment spinning up at http://34.220.99.64:8080. Credentials are admin/admin. Please allow several minutes for bootstrapping and startup.

Hmm... the epehemeral still doesn't have examples. Maybe this PR isn't the root cause?

hmm weird. @eschutho were there any other changes from that and the 4.1 branch?

Oh strange. That was the one that I reverted from 4.1, but let me see what else might have changed.

Ephemeral environment shutdown and build artifacts deleted.
