How to configure nextjs 9 and ant design less compatibility? - reactjs

Question

After upgrading react,react-dom and nextjs this error happens :
Build error occurred

This is my next.config.js:
const nextConfig = {
distDir: '_next',
onDemandEntries: {
maxInactiveAge: 1000 * 60 * 60,
pagesBufferLength: 5,
},
webpack: (config, { dev }) => {
!dev &&
config.plugins.push(
new BrotliPlugin({
asset: '[path].br[query]',
test: /\.js$|\.css$|\.html$/,
threshold: 10240,
minRatio: 0.7,
}),
);
!dev &&
config.plugins.push(
new CompressionPlugin({
filename: '[path].gz[query]',
algorithm: 'gzip',
test: /\.js$|\.css$|\.html$/,
threshold: 10240,
minRatio: 0.7,
}),
);
return config;
},
};
module.exports = withPlugins(
[
[withImages],
[withCss],
[
withSass,
{
cssModules: true,
cssLoaderOptions: {
localIdentName: '[path]___[local]___[hash:base64:5]',
},
},
],
[withBundleAnalyzer],
],
nextConfig,
);
Do you know what is wrong with this?
Edit
It seems there is a compatibility problem with ant design and I found some sources but not get it though!

Based on this example in the Next.js repository
https://github.com/zeit/next.js/tree/canary/examples/with-ant-design
To resolve this problem, add these lines to your next.config.js:
const nextConfig = {
webpack: (config, { isServer }) => {
if (isServer) {
const antStyles = /antd\/.*?\/style\/css.*?/;
const origExternals = [...config.externals];
config.externals = [ // eslint-disable-line
(context, request, callback) => { // eslint-disable-line
if (request.match(antStyles)) return callback();
if (typeof origExternals[0] === 'function') {
origExternals[0](context, request, callback);
} else {
callback();
}
},
...(typeof origExternals[0] === 'function' ? [] : origExternals),
];
config.module.rules.unshift({
test: antStyles,
use: 'null-loader',
});
}
return config;
},
};
An example of what the next.config.js file would look like:
const withPlugins = require('next-compose-plugins');
const withCss = require('#zeit/next-css');
const withSass = require('#zeit/next-sass');
if (typeof require !== 'undefined') {
require.extensions['.css'] = file => {};
}
const nextConfig = {
webpack: (config, { isServer }) => {
if (isServer) {
const antStyles = /antd\/.*?\/style\/css.*?/;
const origExternals = [...config.externals];
config.externals = [ // eslint-disable-line
(context, request, callback) => { // eslint-disable-line
if (request.match(antStyles)) return callback();
if (typeof origExternals[0] === 'function') {
origExternals[0](context, request, callback);
} else {
callback();
}
},
...(typeof origExternals[0] === 'function' ? [] : origExternals),
];
config.module.rules.unshift({
test: antStyles,
use: 'null-loader',
});
}
return config;
},
};
module.exports = withPlugins(
[
[withCss],
[
withSass,
{
cssModules: true,
cssLoaderOptions: {
localIdentName: '[path]___[local]___[hash:base64:5]',
},
},
],
],
nextConfig,
);
