Webpack schema not validating correctly

I don't have any issues reported when using similar configuration (with

"webpack": "4.41.6"

):

Please share your webpack configuration file

Please share a file itself, not a screenshot

Sorry about that, this is my webpack file:

const webpack = require( 'webpack' );
const HtmlWebpackPlugin = require( 'html-webpack-plugin' );
const { CleanWebpackPlugin } = require( 'clean-webpack-plugin' );
const WebpackChunkHash = require( 'webpack-chunk-hash' );

const CopyWebpackPlugin = require( 'copy-webpack-plugin' );
const SWPrecacheWebpackPlugin = require( 'sw-precache-webpack-plugin' );
const packageJson = require( '../package.json' );

thank you! still no luck in reproducing the issue (checked in 2019.3.3 and 2020.1 EAP):

Did you try invalidating caches (File > Invalidate caches, Invalidate and Restart)? Can you reproduce the issue in a new project?

What IDE version do you use? looks similar to https://youtrack.jetbrains.com/issue/WEB-43117, that is fixed in 2019.3.2

Hello, updating it to 2019.3.3 seems to have fixed it! Thanks
