Got error when use webrtc-star

Help
1

I setup my ipfs node in Node environment just like the example js-ipfs/examples/browser-exchange-files at master 路 ipfs/js-ipfs 路 GitHub does.

 const node = await IPFS.create({
    repo: './ipfs_database/ipfs2',
    config: {
      Addresses: {
        Swarm: [
          '/dns4/wrtc-star1.par.dwebops.pub/tcp/443/wss/p2p-webrtc-star',
          '/dns4/wrtc-star2.sjc.dwebops.pub/tcp/443/wss/p2p-webrtc-star',
          '/ip4/127.0.0.1/tcp/13579/wss/p2p-webrtc-star'
        ]
      },
      // If you want to connect to the public bootstrap nodes, remove the next line
      Bootstrap: []
    }
  })

Got error when I start it:

Can鈥檛 I use the webrtc-address in Node environment? It鈥檚 weird cause it works well in js-ipfs/examples/browser-exchange-files at master 路 ipfs/js-ipfs 路 GitHub.

The package.json of my demo is very simple:

{
  "name": "demo",
  "version": "1.0.0",
  "description": "demo",
  "main": "index.js",
  "scripts": {
    "start": "node peer1.js"
  },
  "author": "Charles Liu",
  "license": "MIT",
  "dependencies": {
    "ipfs": "^0.52.2"
  }
}

the ipfs verison is ipfs@0.52.3

I also tried run in electron and got same error, so it seems only browser support specifying webrtc-star in swarm address?
