Could not render to pson: undefined method 'merge' for []:Array

[Micah Martin]

This ones got me absolutely scratching my head. I'm trying to created a custom type for managing couchbase. It may not be the right approach but I'm a total noob and I'm trying to figure this thing out. Here's what I have:

/Puppet/manifests/site.pp

node 'qamachine' {

include webserver

}

/Puppet/modules/webserver/init.pp

class webserver {

couchbase { 'test': }

}

/Puppet/modules/couchbase/lib/puppet/type/couchbase.rb

Puppet::Type.newtype(:couchbase) do

newparam(:name) do

isnamevar

end

end

/Puppet/modules/couchbase/lib/puppet/provider/couchbase/couchbase.rb

Puppet::Type.type(:couchbase).provide(:couchbase) do

end

When I try to update the machine this is what I get:

ge' for []:Array

when I remove the call to couchbase in the init.pp file it works fine.

I'm having this issue as well, with a nearly identical stack trace (I'm running on RHEL, however).

Anyone have any ideas?

I stuck some debugs inside my provider methods, but they don't ever seem to get executed.

I restarted my puppetmaster and this seemed to resolve the issue. Very strange message, though. I suppose if I've defined a new type, but haven't restarted puppetmaster it throws a message like this? I will need to test that though
