How to make loot tables work in 1.14?

I've been trying to set up a loot table for a chest. For some reason it doesn't work.
I put the .json file into "datapacks/loottables/data/minecraft/loot_tables/chests/".
There is a "pack.mcmeta" file in the correct folder right next to the data folder. The game does list this datapack when running the command /datapack list.
I named the file "buried_treasure.json".

Here is the command I used: /setblock ~ ~ ~ chest{LootTable:"minecraft:loot_tables/chests/buried_treasure.json"}
The chest comes out empty.

Here is the json file:

{
  "type": "minecraft:chests",
  "pools":
  [
    {
      "rolls":
      {
        "min": 1,
        "max": 4
      },
      "entries":
      [
        {
          "type": "item",

            }
          ]
        },
        {
          "type": "item",
          "name": "minecraft:iron_boots",
          "weight": 6,
          "functions":
          [
            {
              "function": "set_count",
              "count": 1
            }
          ]
        }
      ]
    }
  ]
}

Apparently the solution is as simple as changing the loot table name from

"minecraft:loot_tables/chests/buried_treasure.json"

to

"minecraft:chests/buried_treasure"

Now everything appears in the chest as things should.
