Method Deprecated error when using conversations_history

[skeletonlander]

Run this simple program:

# frozen_string_literal: true
require 'slack-ruby-client'

Slack.configure do |config|
  config.token = ENV['SLACK_API_TOKEN']
  raise 'Missing ENV[SLACK_API_TOKEN]!' unless config.token
end

client = Slack::Web::Client.new
client.auth_test

client.conversations_history(channel: '#somechannel')

And it will produce this error:

/usr/bin/bundle exec /usr/bin/ruby /Users/lorenanderson/ruby_slack/test_slack.rb

The error is being produced by this API helper class:

# frozen_string_literal: true
require_relative 'ids.id'

module Slack
  module Web
    module Api
      module Mixins
        module Channels
          include Ids
          #
          # This method returns a channel ID given a channel name.
          #
          # @option options [channel] :channel
          #   Channel to get ID for, prefixed with #.
          def channels_id(options = {})
            name = options[:channel]
            throw ArgumentError.new('Required arguments :channel missing') if name.nil?

            id_for(:channel, name, '#', :channels, 'channel_not_found') do
              channels_list
            end
          end
        end
      end
    end
  end
end

It appears that the use of channels_list, which is deprecated, causes this failure.

[dblock]

You're right, this needs to be reimplemented using a newer method that replaced it.

Note that this is a client-side facility to resolve names to IDs, the underlying APIs don't support #channel. If you specify actual channel IDs here it won't try to call the deprecated method.

@dblock Hi, I'm having the same issue using client.conversations_info(channel: '#general')

client.conversations_info(channel: '#general')
*** Slack::Web::Api::Errors::SlackError Exception: method_deprecated

[dblock]

Someone please PR a fix.
