KeyError in loader.py upon error.

[jleclanche]

get_bundle defines the following:

            error = u"""
            {error} in {file}
            {message}
            """.format(**assets)

However, upon some webpack errors, my assets dict contained the following:

{
'file': '', 
'message': '(1,24): error TS2307: Cannot find module 'react'.', 
'status': 'error'
}

Therefore, django-webpack-loader crashed, shadowing the root cause of the crash. Was quite frustrating.
I can PR a simple fix that stubs error if it's not in there, but it seems like it's very much supposed to be in there.

The stats/manifest file is read only for webpack-loader. It is supposed to be written to only by webpack and read by django. Django should never write to it.

[jleclanche]

The error is on read.

OK. I suspect you are using webpack config wrong. You should use path option to specify the directory webpack should write to and use filename to specify the name of the file. You are getting wrong results because you are using filename where you should be using path. Check webpack documentation: https://webpack.github.io/docs/configuration.html

Please disregard to previous message. I thought I was replying to something else. Sorry.

@jleclanche This seems to be an issue when using typescript. This has been reported before: django-webpack/webpack-bundle-tracker#12

I'd be happy to accept a PR against webpack-bundle-tracker to fix the root cause.
