trying to make the 'payload' field optional:

        "legacy_server_list_ping": {
          "id": "0xfe",
          "fields": [
            {

                    "0": "ubyte"
                  },
                  "default": "void"
                }
              ]
            }
          ]
        }
        

but testing with https://github.com/PrismarineJS/node-minecraft-protocol/pull/334, when a ping is received:

      throw er; // Unhandled 'error' event
