sendPoll and numbering of the options

[minigo]

Code:
std::vector<std::string> options = {"1","2","3","4"};
bot.getApi ().sendPoll (message->chat->id, "Answers", options, false, 0, std::make_shared<TgBot::GenericReply> (), true, "quiz", false, correct_answer, explanation);

If i set the correct correct_answer value to 0 or 4 i get an error - error: Bad Request: wrong correct option ID specified.

Thanks! If you set the value to 4, an error should appear, because you don't have 5 options
