Can't send menus

[norrisboat]

For some reason all the other types of messages work but menus don't seem to be working for me.
Here is my code:

var text = "How can I help you today?";
var buttons = [
    {
        "type": "postback",
        "title": "Start a New Order",
        "payload": "start_order"
    },
    {
        "type": "postback",
        "title": "Call Us",
        "payload": "call_us"
    },
    {
        "type": "web_url",
        "title": "View Website",
        "url": "http://something.com/"
    },
    {
        "type": "web_url",
        "title": "Download App",
        "url": "http://something.com/"
    }
];
bot.sendButtonMessage(usersId, text, buttons);

I was sending more than the required number of menus. Thanks for this awesome library.

Just had this issue, So i'm guessing the limit is 3? Can we get this added to the docs please?
