Aha! That was it. Seeing that the test script errored out in a cffi call, my next question was going to be a check in those packages. The latest python-cffi package is included in the RDO Liberty repo, so maybe you didn't run yum update after installing the rdo-release RPM. That's something to fix in the documentation, I'll take note of that.

I'm glad it worked for you.

Regards,
Javier
