Puppet users - Jul 2012 - Hiera problem: Can't convert Symbol into String

All,
   I have found very few references to this error so I''m guessing I
must be
doing something wrong. I have just started using hiera and am trying to use 
it in the simplest way possible, I have a class that looks like this:

class app_users2($compresslogs = hiera(''compresslogs'')) {
                                                                   

      #Setup Cronjob for compressing app logs                               
                                                                   
      if $compresslogs == "true" {
                                                                    
        file { "/etc/cron.daily/copyLogs.cron":
                                                                   
          mode => "750",
                                                                    
          ensure => present,                                               
                                                                    
          alias => "compresslogscron",
                                                                    
          source => "puppet:///modules/app_users2/copyLogs.sh"
                                                                     
        }                                                                   
                                                                   
      }                                                                     
                                                                   
}

For the node I''m running this on, hiera returns
''true'' for that value when
I test it out:

$ hiera -c hiera.yaml compresslogs loc="sd" type="app" 
true

I am using the yaml hiera backend and the yaml file this is configured in 
looks like this:

---
family : prod
cluster : prod
compresslogs : true

However, when I try to execute the manifests either on the host or test 
them using cucumber-puppet I get the following error:

err: Could not retrieve catalog from remote server: Error 400 on SERVER: 
can''t convert Symbol into String at 
/etc/puppet/modules/app_users2/manifests/init.pp:2 on node xyz

I have tried quoting, unquoting the data in the yaml file & in the 
conditional in the class. I''ve tried calling hiera as a parameter to
the
class, also just as part of the conditional ( if
hiera(''compresslogs'') ==
true ) etc. It appears that anytime I try to reference that value from 
puppet it throws this error. 

I have found a few references in IRC logs to others having this problem but 
they all stated "Oh, I figured it out" without explaining how - so
I''m a
bit stuck. 

I am running the following hiera versions on the puppetmaster:

hiera-puppet-1.0.0-0.1rc1.el5
hiera-1.0.0-0.1rc3.el5

And the puppetmaster is running puppet v. 2.7.6.-2. I also tried updating 
the puppet version on my host running cucumber-puppet to 2.7.18 and it 
continues to throw this error. 

Any help would be greatly appreciated. 

Thanks,
Aaron
