hiera don't recognize hiera-http

[Bareliah]

Hello,

I have hiera version 1.3.4 and the most recent hiera-http plugin

After I unzip the folder, I installed it and modify hiera.yaml file :

:Backend: ['http']

:http:
:host: couchdb.address
:port: 5984
:output: json
:failure: graceful
:path:

• /dbname/%{clientcert}
• /dbname/%{environment}
• /dbname/document_name

After it I tried to run: hiera -d nameField -c path/of/hiera.yaml and its final result is nil.

Unfortunately, it seems like the plug-in is not recognize by hiera and it search only yaml files.

Help please!
Thanks,
Bar.
