Uncaught Error: write after end

Nobody has claimed this yet.

I have tried to replicate my log using
``` peer.pipe(log.replicate({ live: true })).pipe(peer);```
But get the following error
```index.js:2568 Uncaught Error: write after end
at writeAfterEnd (index.js:2568)
at Encoder.Writable.write (index.js:2612)
at Protocol._encode (index.js:6257)
at Protocol.node (index.js:6231)
at index.js:6362

at IDBTransaction.transaction.oncomplete (index.js:7745)```

I was following the video on
https://www.elastic.co/videos/building-distributed-offline-website-by-mathias-buus

Start by reproducing the reported `peer.pipe(log.replicate({ live: true })).pipe(peer)` flow and inspect the stack in index.js, especially Protocol._encode, Encoder.Writable.write, and the IDBTransaction completion handler. Compare the behavior with the linked video and establish the conditions that cause the write-after-end error; done means the reproduction no longer fails or the remaining incompatibility is clearly documented.
