Hi, we strip sourcesContent from our source maps to reduce bloat and prevent accidentally leaking our unminified source code. Unfortunately when I try to visualize such a source map with this extension, it looks something like this:

The offsets are correct, but the text is missing. Could you try to read the original file(s) if sourcesContent is unavailable? Of course, if they are missing then there isn't much you can do, but in my case the files are accessible.
