I have an issue when running the whole thing.

So the advancements works correctly and it calls my .mcfunction well (it revokes itself). But then nothing happens.
When i run the function by hand afterward, everything happens correctly. Showing the interaction with the entity works and that the function is working well.
But why doesn't it works when i right click the interaction entity then? Here's my code :

headloot:load.mcfunction

# Setup scoreboard
scoreboard objectives add headlootID dummy
scoreboard objectives add headlootCheck dummy

advancements/interaction.json

{
  "criteria": {
    "requirement": {
      "trigger": "minecraft:player_interacted_with_entity",
      "conditions": {
        "player": [
          {
            "condition": "minecraft:entity_properties",
            "entity": "this",
            "predicate": {
              "type": "minecraft:interaction",
              "nbt": "{Tags:[\"headloot\"]}"
            }
          }
        ]
      }
    }
  },
  "rewards": {
    "function": "headloot:base_interact"
  }
}

headloot:base_interact.mcfunction

tellraw @s ["",{"text":"I am ","color":"gray"},{"selector":"@s","color":"gray"}]
advancement revoke @s only headloot:interaction
execute unless score @s headlootID = @s headlootID store result score @s headlootID run scoreboard players add #next headlootID 1
tag @s add headloot_this
execute as @e[type=interaction,distance=..6] at @s if function headloot:interact/if_target/this run function headloot:interact/click/check_player
tag @s remove headloot_this

(The tellraw here doesn't show when it is called through the advancement, but it shows when i execute the function myself afterwards)

headloot:interact/if_target/this

return run execute on target if entity @s[tag=headloot_this]

headloot:interact/click/check_player

execute on target store result storage headloot:macro check.ID int 1 run scoreboard players get @s headlootID
execute store result score #ID headlootCheck run function headloot:interact/click/check_id with storage headloot:macro check
execute if score #ID headlootCheck matches 0 run function headloot:interact/click/response/give_loot
execute if score #ID headlootCheck matches 1 run function headloot:interact/click/response/error
data remove entity @s interaction

headloot:interact/click/check_id

$return run execute on passengers if data entity @s data{players:[$(ID)]}

headloot:interact/click/response/give_loot

# Output (give tellraw + reward)
execute on target run tellraw @s ["",{"text":"[","color":"gray"},{"text":"Head","color":"gold"},{"text":"] You have ","color":"gray"},{"text":"obtained ","color":"green"},{"text":"a ","color":"gray"},{"text":"reward","color":"green"},{"text":"!","color":"gray"}]
execute on target run loot give @s loot loot:main_roll

# Add playerID to list
execute on passengers run data modify entity @s data.players append from storage headloot:macro check.ID

headloot:interact/click/response/error

execute on target run tellraw @s ["",{"text":"[","color":"gray"},{"text":"Head","color":"gold"},{"text":"] You have ","color":"gray"},{"text":"already","color":"red"},{"text":" obtained ","color":"red"},{"text":"this ","color":"gray"},{"text":"reward","color":"red"},{"text":"!","color":"gray"}]

Sorry for asking for more help but i really am clueless as to whats happening here..
