I could solve the issue by using resolve-url-loader module. It can help to somebody Below is part of webpack.js

{
test: function (fileName) {
return !fileName.endsWith('.module.scss') && fileName.endsWith('.scss') // just regular .scss
},
use: [
{
loader: '@microsoft/loader-load-themed-styles',
options: {
async: true
}
},
{
loader: 'css-loader',
options: {
sourceMap: true
}
}, // translates CSS into CommonJS
'resolve-url-loader',
{
loader: 'sass-loader',
options: {
sourceMap: true
}
} // compiles Sass to CSS, using Node Sass by default
]
}
