TypeError: Cannot create property 'colors' on string 'errors-only'

If I set stats: 'errors-only', I get this error:

TypeError: Cannot create property 'colors' on string 'errors-only'
    at [appFolder]\node_modules\webpack-stream\index.js:62:31

webpack itself is fine with it, so is karma-webpack. It's only webpack-stream that has a problem

Yeah, looks like the code right here is assuming it's not using shortcut strings

webpack-stream/index.js

Lines 58 to 64 in 505ad81

	var statsOptions = (options && options.stats) || {};
	Object.keys(defaultStatsOptions).forEach(function (key) {
	if (typeof statsOptions[key] === 'undefined') {
	statsOptions[key] = defaultStatsOptions[key];
	}
	});
