"Cannot read property 'replace' of undefined" in the overlay.

[scriptex]

I am experiencing a weird issue with this webpack plugin.
I am not sure what causes this because it occurs randomly but I noticed that it happens when:

1. A path to an external asset (png, svg, or scss file) is changed
2. A variable or property in the redux store is changed

The console output is not so helpful but I will paste it here:

Uncaught TypeError: Cannot read property 'replace' of undefined
    at CompileErrorTrace (CompileErrorTrace.js?88cb:25)
    at CompileErrorContainer (CompileErrorContainer.js?ee76:21)
    at eval (index.js?5a19:184)
    at ensureRootExists (index.js?5a19:139)
    at render (index.js?5a19:172)
    at showRuntimeErrors (index.js?5a19:294)
    at eval (utils.js?6b9c:23)

The same error is being thrown over and over until I reload my browser. Then the build crashes and I see white screen.

Here is a screenshot from the browser console:

I have updated to version 0.5.0-rc.2 but the same issue occurred with the previous version I was using (0.4.3).

Any help will be highly appreciated.

Edit: Maybe it's worth mentioning that I am using React and Redux with TypeScript in a custom Webpack configuration.
If needed I can provide parts of the Webpack config file which might be relevant for you to debug.

Hi, please provide a reproduction - it is impossible for me to debug.

Alternatively, can you print out what errors are captured by the error overlay? There must be some other error triggering it right?
