Customerio::BaseClient does not support GET endpoints - "::InvalidRequest: Invalid request method :get when fetching collections"

[ishields]

It appears that the customer io client does not support GET requests. The endpoint to fetch collections is a GET and so this fails.

Example usage:
@client.request_and_verify_response(:get, "/v1/api/collections")

Endpoint I am trying to use.

# /.rvm/gems/ruby-3.4.2/gems/customerio-5.3.0/lib/customerio/base_client.rb:68
def request_class(method)
      case method
      when :post
        Net::HTTP::Post
      when :put
        Net::HTTP::Put
      when :delete
        Net::HTTP::Delete
      else
        raise InvalidRequest.new("Invalid request method #{method.inspect}")
      end
end
