Error looking up key in version 2.0.0

[f0xtek]

Hi,

There seems to be an issue looking up keys over http with version 2.0.0.

I perform hiera lookup with 'hiera -c hiera.yaml -d keyName' and get the following error:

/usr/lib/ruby/gems/1.8/gems/hiera-http-2.0.0/lib/hiera/backend/http_backend.rb:28: warning: multiple values for a block parameter (2 for 1)

        from /usr/bin/hiera:225

This doesn't happen in hiera-http version 1.4.0. I am using ruby version 1.8.7.

I get the same error, and version 1.4.0 does not work for me because I need to pass a token to the HTTP API. Please fix this. Thanks!

@drmarconi @xescab Can you show your configuration from hiera.yaml please?

Hi,

My hiera config would be as follows:

:http:
    :host: <ip_address>
    :port: <port>
    :output: json
    :failure: graceful
    :paths:
        - /path/to/endpoint

Thanks
