When running on puppet 5.5.16 on Redhat linux 7 it fails.

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Unknown function: 'random_password'. (file: ....modules/cerebro/manifests/params.pp, line: 6, column: 72) on ...

You're missing the puppet/extlib module, which provides the random_password function
