Illegal argument "type" sent in all requests upgrading to 8.x

[cjba7]

Aloha,

The ruby API gem, 'elasticsearch-api', alongside this gem seem to send a parameter on all requests when using 8.5 (also tested on 8.4 and 8.3).

At present I've got 7.5.0 in the Gemfile and all works as expected with an ES8.5 cluster.

Working

Gemfile
gem 'elasticsearch', '7.5.0'
gem 'elasticsearch-api', '7.5.0'
gem 'elasticsearch-model'
gem 'elasticsearch-rails'

Gemfile.lock
elasticsearch (7.5.0)
  elasticsearch-api (= 7.5.0)
  elasticsearch-transport (= 7.5.0)
elasticsearch-api (7.5.0)
  multi_json
elasticsearch-model (7.2.1)
  activesupport (> 3)
  elasticsearch (~> 7)
  hashie
elasticsearch-rails (7.2.1)
elasticsearch-transport (7.5.0)
  faraday (>= 0.14, < 1)
  multi_json

Kerploding

Gemfile
gem 'elasticsearch', '8.5.0'
gem 'elasticsearch-api', '8.5.0'
gem 'elasticsearch-model'
gem 'elasticsearch-rails'

Gemfile.lock
elastic-transport (8.1.0)
  faraday (< 3)
  multi_json
elasticsearch (8.5.0)
  elastic-transport (~> 8)
  elasticsearch-api (= 8.5.0)
elasticsearch-api (8.5.0)
  multi_json
elasticsearch-model (7.1.1)
  activesupport (> 3)
  elasticsearch (> 1)
  hashie
elasticsearch-rails (7.2.1)

Example

Traceback (most recent call last):

type appears to be added here: https://github.com/elastic/elasticsearch-rails/blob/main/elasticsearch-model/lib/elasticsearch/model/searching.rb#L57-L59

However we can see here in the comments the allowed parameters does not allow type: https://github.com/elastic/elasticsearch-ruby/blob/main/elasticsearch-api/lib/elasticsearch/api/actions/search.rb#L26-L72

Main reason for our upgrade

We need to start using ES Cloud ID and API key which, according to Elasticsearch support, is not supported in gems of 7.5 versions.

Damn. Also stucked with this problem in the middle of update of 'elasticsearch' gem and updating to Elasticsearch 8.7.0 :(
Any solution/fork yet?
