Further explaining what Alexander said Examples: /execute at @s[nbt={Dimension:0}] run say test | Will not work /execute at @s[nbt={}] run say test | Will work /execute at @e[type=skeleton,name="Tester",nbt={HurtTime:4s}] run say test | Will not work So anything testing NBT will not work and there will not be an error message.
