Other

This is the loot table I am using from the data pack:

{
"pools": [
{
"rolls": 1,
"entries": [
{
"type": "minecraft:item",
"name": "minecraft:paper",
"conditions": [
{
"condition": "minecraft:match_tool",
"predicate": {
"tag": "minecraft:pickaxes"
}
}
]
}
]
}
]
}

Start with the LootTable#populateLoot API and the LootContext.Builder usage shown in the reproduction. Trace how required parameters are validated for the supplied block location and compare that behavior with the documented API contract. Done means the provided context no longer produces the reported missing-parameters error, with coverage for this reproduction if an existing test area is identified.
