Error while subscribing on Level2 Market data

[xorium]

I've tried to connect and subscribe to the Level2 data.But after successful connection and sending subscribe message (tried message from doc):

{
    "id": 1545910660740,                          
    "type": "subscribe",
    "topic": "/market/level2:BTC-USDT",
    "response": true                              
}

I'm getting the next error message: {"code":400,"data":"data format is invalid","id":"Htq95uqNXc","type":"error"}

Can you fix this or my be update documentation? Thank you!
