Description:

Adding dht to libp2p configuration causes crash:

         services: {
            identify: identify(),
            pubsub: gossipsub({ allowPublishToZeroPeers: true }),
            dht: kadDHT()
        }

TypeError: Cannot destructure property 'kBucketSize' of 'init' as it is undefined.

Steps to reproduce the error:

Just define dht: kadDHT() in services{}

I think this could use a more helpful error message, but as of v12.x.x you need to configure the KadDHT module to tell it about your DHT configuration.

For example, how to connect to the public Amino/IPFS DHT, or how to connect to a local, LAN-only DHT.

dht: kadDHT({ kBucketSize: 20, }),

should fix issue
