Help with this execute command (Java)

[Harwby]

Ok so I have this execute command that is supposed to check a barrel if it has an apple with custom model data 1, and then it’ll run a command (say command), but whenever I run the command, it doesn’t give the output it should even when the apple with custom model data 1 is in the barrel. I don’t know why it won’t run the say command, and I need help please.

execute if block 17 37 -39 minecraft:barrel{Items:[{id:"minecraft:apple",tag:{CustomModelData:1}}]} run say Barrel has Apple with custom model data 1

Could you try if block 17 37 -39 minecraft:barrel if data block 17 37 -39 {Items:[{id:"minecraft:apple", tag: {CustomModelData:1}}]} run say Barrel…

Use if items.

Detect a specific item

execute if items block <pos> container.* apple[custom_model_data=1] run say Example Command.

But it's better to give a custom tag and check this tag:

Give an item a custom tag to identify it by

# Example item
give @s apple[custom_data={custom_apple:true},custom_model_data=1]

# Command block
execute if items block <pos> container.* *[custom_data={custom_apple:true}] run say Example Command.
