reply_markup -> 400 Bad Request

[dpblnt]

I would like to use this lib, it's fast and reliable, but unfortunately for the following code:

api.sendMessage(this_chat_id, "...",
{
	"parse_mode"=> "Markdown",
	"reply_markup"=>{
		"keyboard"=>[["1", "2"]],
		# Other optional settings:
		"resize_keyboard"=>true,
		"one_time_keyboard"=>true,
		"selective"=>true,
		"force_reply"=>true
  # "hide_keyboard"=>true
	}
})

I get this reponse::

Any hints?

Also for

api.sendMessage(this_chat_id, "the message", {"parse_mode"=> "HTML"})

i get

Could it be the same issue? Could it by my system?
