"deals_damage" field doesn't work on player entity

I was trying to build a blocking skill with “minecraft:damage_sensor”. Here’s the JSON

        }
      }
    }
  }
}

Someone have told me that I shouldn’t create 2 triggers for each of “event” and “deals_damage”. But actually, I first tried to put them into same trigger only find it in vain. So I divided them in 2 same triggers.

Steps to reproduce

1. Open a world with a pack contains the JSON file

2. Type “/tag @s add gm:blocking” and enter in the chat box

3. Summon a zombie to attack you

Expected result

Anvil sound is played, no damage applied

Observed result

Anvil sound is played, damage is applied
