Upgrade from puppet 5 to puppet 6

[Aditya Gupta]

Hello All,

Recently i have updated from puppet-5 to puppet-6 but after upgrade my erb stop working.

It is throwing error:

Error: Error while evaluating a Function Call, undefined method `[]' for Puppet::Pops::Loader::RubyLegacyFunctionInstantiator::Puppet:Module 

Simple resource: 

    file { '/etc/libvirt/libvirtd.conf':

        ensure  => file,

        path    => '/etc/libvirt/libvirtd.conf',

        content => template('kvm/libvirtd.conf.erb'),

    }

Please suggest.

Thanks,

Aditya

providing the erb template would be valuable, if possible.

The error looks like someone defined new constants w/in a custom function file.

Is your erb file calling a custom function?

That sounds like the server isn't compiling the code that you think it is. Can you first restart puppetserver to ensure that it's not just cached, and then check that you're deploying code correctly and that you're using the right environment, etc.

Also, try commenting out the resource causing the problem and just ensure that you're even looking at the right code!

Have you changed the content of the included template function or written your own?

If not I would assume it's coming from this line: https://github.com/puppetlabs/puppet/blob/master/lib/puppet/parser/functions/template.rb#L15

However, I can't imagine the Puppet module being undefined when loading a ruby function.

Is this running within Puppet Server as a normal catalog compilation or is this happening when executing a different tool that might bootstrap Puppet differently?
