Почему webpack не компилирует Sass-файлы?

Добрый день!
Подскажите, пожалуйста, почему при компиляции scss-файлов, в которых присутствует backgroung:('../src), webpack выдает ошибку:

ERROR in ./~/css-loader!./~/sass-loader/lib/loader.js!./~/resolve-url-loader!./src/components_test/menu/menu.scss
Module not found: Error: Can't resolve '../src/img/header/header_bg.jpg' in 'D:\STUDY\Development site\My work\Portfolio\src\components_test\menu'
 @ ./~/css-loader!./~/sass-loader/lib/loader.js!./~/resolve-url-loader!./src/components_test/menu/menu.scss 6:104-146
 @ ./src/components_test/menu/menu.scss
 @ ./src/components_test/menu/menu.js

Конфиг и json ниже:
