Everytime I do the CanPlaceOn command it says i'm wrong

Question

My command is

/give @p lever 1 0 {"can_place_on" : {"blocks" : ["diamond"]}}

and it keeps responding by saying

Component 'can_place_on' is not a supported component.

What did I do wrong?

Answer 1

You probably mean diamond_block.

/give @p lever 1 0 {"can_place_on":{"blocks":["diamond_block"]}}
