      The bug

      When giving an effect to an op using the /effect give command all ops are kicked from the server. The kick message is:

      Internal Exception: io.netty.handler.codec.DecoderException:com.google.gson.JsonParseException: Don't know how to return {} into a Component
      

      How to reproduce

      You have to be opped on the server:

      /effect give {playerName} minecraft:{effectName}
      

      this then kicks all ops who are on the server but not non-opped members. This also happens if you include the seconds/amplifier/hide particles.
