How do i intercept end crystal damage? | latcord | Page 1

I'm trying to make it so the player cant break an end crystal from too far away. This script doesnt even say hi, and the entityevents.death doesnt either.

EntityEvents.hurt('minecraft:end_crystal', event =>{

    //debug comments----
    event.server.tell('hi')
    event.server.tell(event.source.actual.name.getString())
    event.server.tell(event.source.actual.distanceToEntity(event.entity).toString())
    //----

    if (event.source.actual.distanceToEntity(event.entity) < 5){
        event.cancel
    }
})
