undefined method `value' for nil:NilClass

[treydock]

I'm getting this error when I try to decrypt data either via hiera command line tool or via eyaml command line tool. Thus far I don't seem to get errors when puppetserver decrypts the data. The system is RedHat 6.

Full --trace output of eyaml decrypt:

# eyaml decrypt -n gpg --gpg-gnupghome=/etc/puppet/secure/keys/gpg --file=/etc/puppet/hiera/production/hieradata/fqdn/FQDN-OMIT.yaml  --gpg-recipients=puppet@DOMAIN --trace
