Could not autoload puppet/type/cups_queue

[cmseal]

Given Fedora 27 with Puppet 5.5.8 and CUPS 2.2.4.

When I apply the manifest

include '::cups'

cups::resources:
  lab001:
    ensure: printer
    accepting: true
    access:
      policy: allow
      users: ['all']
    description: "Lab001"
    enabled: true
    held: false
    location: "London site"
    make_and_model: "Zebra CPCL Label Printer"
    shared: false
    uri: socket://lab001.lon.example.com:9100
  lab002:
    ensure: printer
    accepting: true
    access:
      policy: allow
      users: ['all']
    description: "Lab002"
    enabled: true
    held: false
    location: "London site"
    make_and_model: "Zebra CPCL Label Printer"
    shared: false
    uri: socket://lab002.lon.example.com:9100

In order to setup printers using hiera

Then I get the error message:

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Function Call, Could not autoload puppet/type/cups_queue: /etc/puppetlabs/code/environments/production/modules_3rdparty/cups/lib/puppet/type/cups_queue.rb:104: unknown type of %string

The version of (J)Ruby your Puppet Server is running on is too old to understand the %i percent literal. This means you are using a version of Ruby which has already reached its end-of-life.

Also, this code was added to the module after the latest release which means you are working with a forked or cloned version of the module.

@leoarnold thanks for taking the time to explain it. Much appreciated!

This is an issue on any servers running puppet 4. They use their own built in ruby which at the moment is: /opt/puppetlabs/puppet/bin/ruby --version
ruby 2.1.9p490 (2016-03-30 revision 54437) [x86_64-linux]

I am running puppet 4.10.12 on Debian 8 which are both listed as compatible in the forge module version 2.2.0.

@tparkercbn The percent literal was already available in Ruby 2.0.0: https://docs.ruby-lang.org/en/2.0.0/syntax/literals_rdoc.html#label-Percent+Strings

[tparkercbn]

I agree, so I'm not sure why it's breaking. This is with module version 2.2.0 on server 4.12.10 (on Debian 8) and client 4.10.12 (on Debian 8)

@tparkercbn D'Oh: Since Puppet 4, the Puppet Server is written in Clojure and runs on the JVM where it uses some version of JRuby which probably does not support the percent literal.

I dropped the use of percent literals and published version 2.2.1 without it just now.
