Which version does which rabbitmq-plugins give you? Does /sbin/rabbitmq-plugins exist, and is /sbin in the path of the user running Puppet at the time of the run? Does it only fail on the first run, and succeed on subsequent runs (idempotency problem), or does it fail every time (is the example debug output from a single run, or from two consecutive runs)?

Since the code uses which, you may be able to influence this by adjusting the PATH that your puppet run runs under.

If this is with RabbitMQ 3.7.x (which I'm assuming it is from the versions above), this module doesn't explicitly list support for that version yet. As you'll see in the current issues, there are some other issues which may affect later 3.7.x issues like 3.7.9 and later.
