Uncaught Error: Cannot find module './log'

[johan-lejdung]

What is the current behavior?
We recieve a warning in the console:

Uncaught Error: Cannot find module './log'.

    at WebSocketTransport.ws.onmessage (bundle.js:80623)

What is the expected behavior?
No Warning, we are not using hot-reloading.

What we think is happening
The warning is generated from this line. We are not using hot-reloading but it looks like the code think we are.

If we call hotCtx.keys() on line 80 in the commit above we get this array:

["../package.json", "./console", "./formatters"]

Please mention your webpack and Operating System version.
MacOs Sierra
Webpack-dev-server: 2.7.1
Webpack: 3.5.5
