Hi,

Images and icons are not loading properly after extending the theme.
Getting the following error.
[CubaWebScssThemeCreation] Cannot load image: E:\CubaExamples\keansa_cloud\modules\web\build\themes-tmp\VAADIN\themes\havana\components\tabsheet\sprites\next-tab.png due to: Can’t read input file!

Hello!

Could you provide the styling rules that you use and say where your images are located?
