Subscribe ticker for a lot of symbols crashes

[MauriPastorini]

Hi, using websockets when I try to subscribe to a lot of symbols, the library crashes instantaneously.
What can I do please?

Here is my code:

const timeBetweenRequest = 10 * 1000;

const BFX = require("bitfinex-api-node");
const options = {
  ws: {
    autoReconnect: true,
    seqAudit: true,
    packetWDDelay: timeBetweenRequest
  }
};
const bfx = new BFX(options);

const start = symbols => {
  const ws = bfx.ws(2, { transform: false });

  ws.on("open", () => {
    console.log("open");
    for (let x = 0; x < symbols.length; x++) {
      var element = symbols[x];
      ws.subscribeTicker(element);
    }
  });

  ws.onTicker({}, (ticker, info) => {
    console.log("Info: ", info);
    console.log("Ticker: ", ticker);
  });

  ws.open();
};

start(["Pair1", "Pair2", "Pair3", "...."])

Error:

@MauriPastorini can you add an error listener to see what the error actually is? Code:

ws.on('error', (err) => console.log(`error: ${err.message}`))

What version are you using?
Because 18 days ago the models were changed breaking this module.
Can you test if it works with v2.0.0?
