      Using the /kill command only gives the following error:

      [17:23:47] [Server thread/WARN]: Couldn't process command: 'kill @e[type=!Player]'
      [17:23:47] [Client thread/INFO]: [CHAT] An unknown error occurred while attempting to perform this command
      

      How to reproduce

      1. Go in creative mode
      2. Summon any entity that can use a loot table, for example:
        /summon MinecartChest ~ ~ ~ {LootTable:"."}
        
      3. Try to destroy the entity
