Trouble with Spawn Rules

[granite perch]

I am not getting any spawns with the following.json { "format_version": "1.12.0", "minecraft:spawn_rules": { "description": { "identifier": "dw623:tree_spider", "population_control": "animal" }, "conditions": [ { "minecraft:spawns_on_surface": {}, "minecraft:weight": {"default":100}, "minecraft:herd": {"min_size":1,"max_size":4}, "minecraft:brightness_filter": {"min":0,"max":15,"adjust_for_weather":false}, "minecraft:biome_filter": {"test":"has_biome_tag","operator":"==","value":"animal"}, "minecraft:spawns_on_block_filter": [ "minecraft:podzol", "minecraft:grass_path", "minecraft:coarse_dirt", "minecraft:short_grass", "minecraft:tall_grass", "minecraft:fern", "minecraft:large_fern", "minecraft:acacia_leaves", "minecraft:birch_leaves", "minecraft:cherry_leaves", "minecraft:jungle_leaves", "minecraft:dark_oak_leaves", "minecraft:mangrove_leaves", "minecraft:oak_leaves", "minecraft:spruce_leaves", "minecraft:vine", "minecraft:sweet_berry_bush", "minecraft:mangrove_roots", "minecraft:acacia_log", "minecraft:birch_log", "minecraft:cherry_log", "minecraft:dark_oak_log", "minecraft:jungle_log", "minecraft:mangrove_log", "minecraft:oak_log", "minecraft:spruce_log", "minecraft:poppy", "minecraft:blue_orchid", "minecraft:allium", "minecraft:azure_bluet", "minecraft:red_tulip", "minecraft:orange_tulip", "minecraft:white_tulip", "minecraft:pink_tulip", "minecraft:oxeye_daisy", "minecraft:cornflower", "minecraft:lily_of_the_valley", "minecraft:dandelion", "minecraft:wither_rose", "minecraft:sunflower", "minecraft:lilac", "minecraft:rose_bush", "minecraft:peony", "minecraft:flowering_azalea", "minecraft:azalea_leaves_flowered", "minecraft:mangrove_propagule", "minecraft:pitcher_plant", "minecraft:torchflower", "minecraft:pink_petals" ] } ] } } besides the blocks. Not much difference from regular animals. I am in a forest, so logs of all these things... and I added grass, for testing and still nothing.

I thought spawn rules used 1.8.0 for the format

Also I think the spawns_block_filter should look like this:

      "minecraft:spawns_on_block_filter": [
          { "name": "minecraft:grass_block" },

That is the latest version, I think I got from blockbench created entity add-on

and block filter is string or array per https://learn.microsoft.com/en-us/minecraft/creator/reference/content/entityreference/examples/definitions/nestedtables/spawns_on_block_filter?view=minecraft-bedrock-stable

well 17 may be the latest version, the vanilla files bat has 1.17.0

The others use 8. Imma try 8

pillager patrol uses 1.11.0 and has some weird stuff in it

I’m basing that off the newest armadillo spawn rules on the GitHub assets https://github.com/Mojang/bedrock-samples/blob/main/behavior_pack/spawn_rules/armadillo.json
