Promise rejection warning

UnhandledPromiseRejectionWarning: TypeError: this._libp2p.pubsub.getSubscribers is not a function at PubSubRoom._pollPeers (ipfs-pubsub-room\src\index.js:106:49) at listOnTimeout (internal/timers.js:531:17) at processTimers (internal/timers.js:475:7) (node:5828) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)

I got this error when I made a Room with IPFS node. How to solve this?

I've got the same error with the following code:

import IPFS from 'ipfs';
import Room from 'ipfs-pubsub-room';

const repo = () => (
  `/ipfs/repo/${Math.random()}`
);

// create IPFS node
const ipfs = new IPFS({
  repo: repo(),
  EXPERIMENTAL: {
    pubsub: true,
  },
});

const room = new Room(ipfs, 'ipfs-pubsub-demo');

room.on('peer joined', (peer) => console.log(`peer ${peer} joined`));
room.on('peer left', (peer) => console.log(`peer ${peer} joined`));

ipfs.once('ready', () => ipfs.id((err, info) => {
  if (err) { throw err; }
  console.log(`IPFS node ready with address: ${info.id}`);
}));```

This seems to be because this library is expecting a newer version of js-libp2p. See changelog here: https://github.com/libp2p/js-libp2p/releases (api was changed from libp2p.pubsub.peers to libp2p.pubsub.getSubscribers)

You can solve this issue by downgrading to ipfs-pubsub-room@1.4.1 until the new version of js-ipfs that has the updated js-libp2p has been released.
