How to make block drop itself when it breaks

I tried making the block drop itself when breaks with loot table like this:

{
	"pools": [
		{
			"rolls": 1,
			"entries": [
					{
							"type": "block",
							"name": "my:block",
							"weight": 1
					}
			]
		}
	]
}

and when i break the block in survival mode the game crashes
