"Could not autoload" error in grafana_dashboard with ruby 2.4 on Centos 6

[michal-rybinski]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet:
  3.8.7
• Ruby:
  2.4.1
• Distribution:
  Centos 6
• Module version:
  2.6.3

How to reproduce (e.g Puppet code you use)

class profiles::grafana {
class { '::grafana':
}

grafana_dashboard { 'example_dashboard':
grafana_url => 'http://localhost:3000',
grafana_user => 'admin',
grafana_password => 'password',
}

grafana_datasource { 'influxdb':
grafana_url => 'http://localhost:3000',
grafana_user => 'admin',
grafana_password => 'password',
type => 'influxdb',
url => 'http://localhost:8086',
user => 'admin',
password => 'password',
database => 'graphite',
access_mode => 'proxy',
is_default => true,
}
}

What are you seeing

I had this error when I had ruby 1.8.7 on puppet server, but I've upgraded it to 2.4.1 and restarted the box to make sure all services will use the new one. Firing "ruby -v" shows:
ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux]
so I am not sure what can be wrong here, might it be due to some other dependencies not being met?

What behaviour did you expect instead

catalog compiles fine

Output log

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not autoload puppet/type/grafana_dashboard: /etc/puppet/modules/grafana/lib/puppet/type/grafana_dashboard.rb:21: syntax error, unexpected ':', expecting ')'
newparam(:title, namevar: true) do

Any additional information you'd like to impart

Hi @michal-rybinski, this error messages comes from ruby1.8.3. Do you still have that version on the agent? Also Puppet 3 isn't supported anymore.

[michal-rybinski]

Hi @bastelfreak, Thanks for your response.

Yes, I found that bit online, that's why I decided to upgrade the version on the server.
On agent there is Centos 7 witn ruby 2.0 installed by default (ruby 2.0.0p648 (2015-12-16) [x86_64-linux]) so I guess this should be fine.

The only thing that I found online just a 10 minutes ago is that I haven't done "gem update" after the upgrade, so I am doing it atm and will see if that helps.

Thanks

Sorry closed it by mistake

gem update didn't help unfortunately.
I have no experience with ruby whatsoever, do you have any hints where I might look for potential problems after upgrading ruby versions?

About the Puppet v3 not being supported, I've noticed that that's why I've gone for module version 2.6.3 which it says is the last one that supports it.

Ok, I'played with it for a while and looks like a problem with installing ruby via rvm plus possibly some other dependencies within the OS so I'll just drop managing dashboards ans datasources via this module and will settle for the rest of the functionality till we not migrate to newest versions of OS and Puppet.
