Exception: NoMethodError: undefined method `include?' for nil - in lib/net/http.rb:2466

lib/net/http.rb:2466 の addr_port から開始し、stack trace に示されている Faraday/net_http の呼び出し経路を使って、begin_transport と request を通じてアドレスを追跡します。この経路のどこで nil が入るのかを特定し、意図された失敗時の動作を明確にします。nil のケースが一貫して処理され、回帰チェックでカバーされれば完了です。

I'm getting:

Exception: NoMethodError: undefined method `include?' for nil

Here:

This is the code responsible:

    def addr_port
      addr = address
      addr = "[#{addr}]" if addr.include?(":") # the .include? here
      default_port = use_ssl? ? HTTP.https_default_port : HTTP.http_default_port
      default_port == port ? addr : "#{addr}:#{port}"
    end

It seems there should be some kind of validation earlier to avoid this?
