snow golem are not leaving a trail

the minecraft:trail component is not working. it’s not working for my custom entity at all, and tried snow golems but they aren’t doing it ether even in a cold biome.

"minecraft:trail": {
					"block_type": "test:fake_carpet",
					"spawn_filter": [
						{
							"subject": "self",
							"operator": "==",
							"test": "in_nether",
							"value": false
						}
					]
				}
