I get a strange error when I try to use the command.

I recently started a new world in 1.12.2 with some mods and I added Baritone (standalone ver. for forge) to make things a little easier, but when I tried to start it i got this message:
[Baritone]> mine minecraft:iron_ore
[Baritone]Error at argument #1: Expected y

I have tried writing just "iron_ore" but it gave the same error. This also happened when I tried it with other materials, both vanilla and modded ones.
I would be grateful if someone could tell me why this is happening and how I could fix it.
