How do I restrict the generation of my blocks to only those above the grass or soil? (1.21.1)

I wish they would only appear above land and above water.

A block predicate filter placement type

I tried using it, but I think I was wrong; the filter in question was this one

{
"feature": "techpack:wild_forest_nest",
"placement": [
{
"type": "minecraft:in_square"
},
{
"type": "minecraft:heightmap",
"heightmap": "WORLD_SURFACE"
},
{
"type": "minecraft:block_predicate_filter",
"predicate": {
"type": "minecraft:any_of",
"predicates": [
{
"type": "minecraft:not",
"predicate": {
"type": "minecraft:matching_blocks",
"blocks": "minecraft:water"
}
}
]
}
}
]
}

That's just checking if the block it's trying to generate in is not water, not the block below it. You need to add an offset to the matching blocks check

y = -1?

I'm going to open my modpack

i finded the error

In the file included in the modpack, the filter order was reversed, which caused the feature not to appear

[unkempt osprey]

I changed the order of "any of" to "not"

If anyone needs a generation configuration similar to mine, where the block only appears above the grass and not above the water, it's here. (its a placed feature, the configured its a simple state provider)
