why this predicate doesnt work?

[simple kettle]

tick as @a:

execute as @s[predicate=apex:forward_input] run say forward

forward_input predicate:

{
"condition": "minecraft:entity_properties",
"entity": "this",
"predicate": {
"type_specific": {
"type": "minecraft:player",
"input": {
"forward": true
}
}
}
}
