How to use the libp2p-interfaces/src/crypto/errors.UnexpectedPeerError function in libp2p-interfaces

// Get the Exchange message
  const response = (await lp.decode.fromReader(shake.reader).next()).value
  const id = Exchange.decode(response.slice())
  log('read pubkey exchange from peer %j', remoteId)

  let peerId
  try {
    peerId = await PeerId.createFromPubKey(id.pubkey.Data)
  } catch (err) {
    log.error(err)
    throw new InvalidCryptoExchangeError('Remote did not provide its public key')
  }

  if (remoteId && !peerId.isEqual(remoteId)) {
    throw new UnexpectedPeerError()
  }

  log('plaintext key exchange completed successfully with peer %j', peerId)

  shake.rest()
  return {
    conn: shake.stream,
    remotePeer: peerId
  }
}
