Unhandled rejection error on followers when log is not initialized

[andyautida14]

I ran example/index.js on my local machine without any modification on Node.js version 8.11.4. I think the error happens when the followers receive a packet with type "append" from the leader and log replication is not enabled.

Here's the logs:

(node:19891) 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: 101)

This is happening with log replication initialized as well. Did you find a solution?

I am doing the following hack in the library.
raft.log = options.Log;
