Can somebody please help and see why the tests fail? I don't see any message that I can link to the change I did.

Here is your error: https://travis-ci.com/github/puppetlabs/puppet_litmus/jobs/447303410#L1309

I'm pushing a fix for travis to show/detect that better at 5d532c9

If you had enabled "Allow edits from maintainers" I could have added it here to have you be able to work with it directly.

[hajee]

Thanks David. I'll fix it.

Thank you so much for this patch!

[hajee]

My pleasure. Is there an ETA when this will be released?
