How to quickly & easily debug webpack errors?

Is it just me…or are the errors webpack prints sometimes difficult to decipher what file (and line #) is causing the problem?

For example, in one of my .scss files, I had the following incorrect declaration:

background: rgba(0,0,0,0.7) url(data:image/ png;base64,iVBORw0KGgoAGGDAANSUhEUgAAAAMAAAACCAYAAACddGYaAAAAD0lEQVQIW2NkQABjRmQOAAM+AGkQsDBSAAAAKJHHkC) repeat;

I eventually traced down the error: I had space between image/ png;base64

However, it took me a long time because the error seemed generic and did not specifically state the file & line #.
