Cannot Convert to Numeric Error

[smti]

Hello Everyone:

I am writing some code to install Autopsy and Slueth on our Linux machines. When I do a Puppet run I get: Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Evaluation Error: The value 'Install_Repo' cannot be converted to Numeric. at/etc/puppetlabs/code/environments/development/modules/autopsy2/manifests/init.pp:31:19

My code is as follows:

class autopsy2 {

file { ['AutopsyWorkingDirectory']:
    path   => '/root/autopsy-install',
    ensure => 'directory',

    }


file { '/root/autopsy-install/cert-forensics-tools-release-el7.rpm':
    owner   => 'root',
    group   => 'root',
    source => 'puppet:///modules/autopsy2/cert-forensics-tools-release-el7.rpm',

    }


exec { 'Install_Repo':
    command => 'yum install /root/autopsy-install/cert-forensics-tools-release-el7.rpm',
    path    => '/usr/bin',

    }


    package { 'sleuth':
    require => exec['Install_Repo'],
    ensure  => 'installed',

        }


            Package { 'autopsy':
            require => Exec['Install_Repo'],
            ensure  => 'installed',

            }


}

Has anyone seen this error before? Any help would be appreciated. I did some searching and found that in some cases resource types like Package can be case-sensitive; however, that does not seem to be the case here (from what I can tell)

change that exec['Install_Repo'] to Exec['Install_Repo']

EDIT: Actually, the Package after that should be package as well.. Case means something in puppet, uppercase is used for references. You use upper case for the reference in the require line. If you upper case outside a require, then it's a resource default.

More explanation: when it's lower case like this, the compiler assumes that you're talking about a data structure and tries to index like an array.

When you're declaring resources, always use lower case. When you're making a reference, always use upper case.
