Puppet / PUP-9944 Catalog Compilation Fails on Empty Class String Issue Type: Task Assignee: Unassigned Created: 2019/08/08 1:25 PM Priority: Normal Reporter: Michael Hashizume Hello! Our team recently upgraded from PE 2017 to PE 2018. After the upgrade, we started encountering this error: michael.hashizume@bfs-hyperv-1-prod:~$ sudo puppet agent -t Info: Using configured environment 'production' Info: Retrieving pluginfacts Info: Retrieving plugin Info: Retrieving locales Info: Loading facts Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Method call, Cannot use empty string as a class name (file: /etc/puppetlabs/code/environments/production/manifests/site.pp, line: 1, column: 43) on node bfs-hyperv-1-prod.it.puppet.net Warning: Not using cache on failed catalog Error: Could not retrieve catalog; skipping run We classify our nodes purely in Hiera. We like this setup because it allows us to keep everything in the codebase, even if nodes only need the base profile applied to them. Our main manifest looks like this: lookup('classes', Array[String], 'unique').include   node default { include profile::base } And the node's Hiera file looks like this: --- classes: '' The node is running Puppet 5.3.5, and the Master is on 5.5.16. Thank you! Add Comment

Re: Catalog Compilation Fails on Empty Class String Classes must be an array and an empty string is certainly not an array. You need to change your data file. --- classes: [] Is how to make the classes key have an empty array value
