So, I am trying to do something with a list (array) of users from hieara. 
 Here is the yaml:

profile::sysconfig::sftp_users: [ "joe", "bill", "nancy" ]


In my profile I have a defined class "debugUsers" that I am calling with 
the array I got from hiera:

class profile::sysconfig::sftpserver {
>   define debugUsers {
>     notify { "username: \"${user}\"": }
>   }
>   class doWork {
>     $users = hiera('profile::sysconfig::sftp_users')
>     validate_array($users)
>     debugUsers { $users: }
>   }
>   include doWork

}


>From everything I know and have read that should give me a notify line for 
user in my array.  But it doesn't.  Instead I get this error from the agent:

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: 
> Duplicate declaration: Notify[username: ""] is already declared in file 
> /etc/puppetlabs/puppet/environments/r10k/dev_users/modules/profile/manifests/sysconfig/sftpserver.pp:5;
>  
> cannot redeclare at 
> /etc/puppetlabs/puppet/environments/r10k/dev_users/modules/profile/manifests/sysconfig/sftpserver.pp:5
>  


Why am I getting duplicate null declarations?  If I call out specific 
elements of the array I get back exactly what I would expect:

class profile::sysconfig::sftpserver {
>   class doWork {
>     $users = hiera('profile::sysconfig::sftp_users')
>     validate_array($users)
>     notify { "user1: \"${users[0]}\"": }
>     notify { "user2: \"${users[1]}\"": }
>     notify { "user3: \"${users[2]}\"": }
>   }
>   include doWork

} 


returns this:

Notice: user1: "joe"
> Notice: /Stage[main]/Profile::Sysconfig::Sftpserver::Dowork/Notify[user1: 
> "joe"]/message: defined 'message' as 'user1: "joe"'
> Notice: user3: "nancy"
> Notice: /Stage[main]/Profile::Sysconfig::Sftpserver::Dowork/Notify[user3: 
> "nancy"]/message: defined 'message' as 'user3: "nancy"'
> Notice: user2: "bill"
> Notice: /Stage[main]/Profile::Sysconfig::Sftpserver::Dowork/Notify[user2: 
> "bill"]/message: defined 'message' as 'user2: "bill"' 


I am sure this is something really stupid, but can someone point out what 
I'm doing wrong here?

Thanks,
