Tearing my hair out, trying to figure out what’s wrong with my SASS files. I keep get a “something went wrong reaching…”, with a long filename of sass files, none of which is helpful. My guess is you’re probably using Visual Studio, and using Web Essentials to compile your SASS. To solve this (at least in my case), hunt down the .suo file in the root directory of your website project, and delete it. You’ll need to make sure your hidden files are visible, otherwise you won’t see the .suo file.
