Updated Webpack 2 to 4 and faced issues while building for production

[avxkim]

When i build, i'm getting a following error:

ValidationError: Invalid options object. CSS Loader has been initialised using an options object that does not match the API schema.
 - options has an unknown property 'minimize'. These properties are valid:
   object { url?, import?, modules?, sourceMap?, importLoaders?, localsConvention?, onlyLocals? }
