Portanto, você pode usar `user_agent` como faria normalmente no código Python, em vez de precisar colocar as primeiras letras em maiúsculas como `User_Agent` ou algo semelhante.

Se por algum motivo você precisar desabilitar a conversão automática de sublinhados para hífens, defina o parâmetro `convert_underscores` de `Header` para `False`:

      throw RuntimeException(failure)
    }

    return countRef.get()
  }

          code: Int,
          reason: String,
        ) {
          webSocket.close(1000, null)
