Why did this error appear when I modified the page, the page did not refresh
HMR stopped work after webpack upgrade from 2 to 4
config

webpack4
"webpack-hot-middleware": "^2.12.2"

// dev-server.js
var hotMiddleware = require('webpack-hot-middleware')(compiler, {
    log: () => {}
});
// force page reload when html-webpack-plugin template changes
compiler.plugin('compilation', function (compilation) {
    compilation.plugin('html-webpack-plugin-after-emit', function (data, cb) {
        console.log('html-webpack-plugin-after-emit', data, cb)
        hotMiddleware.publish({ action: 'reload' });
        cb();
    });
});
