The error occurs in /lib/go-imports.coffee at line 31, where a property 'isModified' is accessed on an undefined object. Start by examining the code around line 20-31 to see what variable is expected to hold an editor object. Check how the 'process' function is called and ensure the editor context is properly passed. Run the package in Atom's dev mode to reproduce the issue and verify the fix.
