websocket contract event doesn't work

[l3lackrooz]

I want to watch the event usdt trc20
I ran a full node server with the event plugin service, but i can only see "blockTrigger", "transactionTrigger" and "solidityTrigger"
i can't see contract event and contract log trigger

my config.conf:

`{
event.subscribe = {
native = {
useNativeQueue = true // if true, use native message queue, else use event plugin.
bindport = 5555 // bind port
sendqueuelength = 1000 //max length of send queue
}

path = "/home/dbgames/fullnode/event-plugin/build/plugins/plugin-kafka-1.0.0.zip" // absolute path of plugin
server = "127.0.0.1:50051" // target server address to receive event triggers
#dbconfig="" // dbname|username|password
contractParse = true,
topics = [
    {
      triggerName = "block" // block trigger, the value can't be modified
      enable = true
      topic = "block" // plugin topic, the value could be modified
    },
    {
      triggerName = "transaction"
      enable = true
      topic = "transaction"
    },
    {
      triggerName = "contractevent"
      enable = true
      topic = "contractevent"
    },
    {
      triggerName = "contractlog"
      enable = true
      topic = "contractlog"
    },
    {
      triggerName = "solidity" // solidity block event trigger, the value can't be modified
      enable = true            // the default value is true
      topic = "solidity"
    },
    {
      triggerName = "solidityevent"
      enable = false
      topic = "solidityevent"
    },
    {
      triggerName = "soliditylog"
      enable = false
      topic = "soliditylog"
    }
]

filter = {
   fromblock = "" // the value could be "", "earliest" or a specified block number as the beginning of the queried range
   toblock = "" // the value could be "", "latest" or a specified block number as end of the queried range
   contractAddress = [
       "TVkNuE1BYxECWq85d8UR9zsv6WppBns9iH" // contract address you want to subscribe, if it's set to "", you will receive contract logs/events with any contract address.
   ]

   contractTopic = [
       "" // contract topic you want to subscribe, if it's set to "", you will receive contract logs/events with any contract topic.
   ]
}

}
my socket.js file :
var zmq = require('zeromq')
, sock = zmq.socket('sub');

sock.connect('tcp://127.0.0.1:5555');
sock.subscribe('blockTrigger');
sock.subscribe('transactionTrigger');
sock.subscribe('contractLogTrigger');
sock.subscribe('contractEventTrigger');

sock.on('message', function(topic, message) {
console.log(new Buffer(topic).toString('utf8'), new Buffer(message).toString('utf8'));
});
