Just started using elasticsearch-ruby. I am trying to get my feet wet with a basic test, but I don't make any progress. That's what I have:

Elastic 5.3.0 in a Docker, working nicely with Kibana and curl on the console.

When I start the rails console I do the following:

> require 'elasticsearch' =\> false  
> client = Elasticsearch::Client.new log: true =\> =\> #\<Elasticsearch::Transport::Client:0x00558b5c6d58c0 arguments={:log=\>true, :logger=\>#\<Logger:0x00558b5c6d5780 @level=0, progname="elasticsearch", default\_formatter=#\<Logger::Formatter:0x00558b5c6d5730 datetime\_format=nil\>, formatter=#Proc:0x00558b5c6d54d8@/usr/local/bundle/gems/elasticsearch-transport-5.0.4/lib/elasticsearch/transport/client.rb:15, logdev=#\<Logger::LogDevice:0x00558b5c6d5690 shift\_period\_suffix=nil, @shift\_size=nil, shift\_age=nil, filename=nil........(had to remov e all @)

> ArgumentError: wrong number of arguments (given 1, expected 0)

Whatever I do (client.search, client.health, client.index) I always get a "**[ArgumentError] wrong number of arguments (given 1, expected 0)**", so I assume something basic is wrong. Any idea what this could be?

Thanks, Tom

Replying to myself here, may this help somebody:

I was able to fix this problem by removing "net-http-persistent" from my Gemfile and remove the adapter: :net\_http\_persistent from client = Elasticsearch::Client.new.

This is not ideal as this kills permanent connections, but good enough for development.
