Service enable - no implicit conversion of false into Array

Is there a stack trace along with the error? Any extra output when running the client in debug mode?

Strange that it happens only sometimes.

Unfortunately, I don't have access to the machine after the error occurs. My build process terminates the instance as soon is an error occurs. Also, I'm running chef from knife-ec2, I'll look into running that in debug mode and stopping the cleanup.

It is very strange, yesterday I hit this error 3 times in 6 tries.

It appears this is actually an issue in chef, not the cron cookbook!

This hit me again today with a completely different service. It was in test kitchen so I was able to view the stack trace. It points to line 134 here - https://github.com/chef/chef/blob/master/lib/chef/platform/service_helpers.rb

The extract_systemd_services shell_out apparently fails causing it to return the false from line 129, which produces the unable to convert boolean to array error when trying to add the two arrays together on line 134.

Yea, that implies that systemctl list-unit-files exits with an error status.

We've reworked the service block in the current version and I'm not seeing a similar error on any platform. Feel free to open this back up if you're still seeing the issue.
