can someone please tell me one thing -- I am getting the following errors on Startup.cs

options.manifest.content['./node_modules/rxjs/Observable.js']['meta'] is an invalid additional property
options.manifest.content['./node_modules/jquery/dist/jquery.js']['meta'] is an invalid additional property
options.manifest.content['./node_modules/rxjs/Subscriber.js']['meta'] is an invalid additional property
options.manifest.content['./node_modules/@angular/core/@angular/core.es5.js']['meta'] is an invalid additional property
options.manifest.content['./node_modules/tslib/tslib.es6.js']['meta'] is an invalid additional property
options.manifest.content['./node_modules/rxjs/util/root.js']['meta'] is an invalid additional property
options.manifest.content['./node_modules/@angular/platform-browser/@angular/platform-browser.es5.js']['meta'] is an invalid additional property ....... etcetcetc

my application is a .Net Core and Angular project and I am getting the above error on the following part --

app.UseWebpackDevMiddleware(new WebpackDevMiddlewareOptions
 
 HotModuleReplacement = true,
 HotModuleReplacementEndpoint = "/dist/__webpack_hmr"
 );

This is the part from my webpack.config. As you can see, the output path is there.

output: 
 filename: '[name].js',
 publicPath: 'dist/' // Webpack dev middleware, if enabled, handles requests for this URL prefix
 ,
 module: {
 rules: [

what does it basically mean?? What is supposed to be done? What package should I update/add/remove to my project?

Thanks in anticipation; I searched around in vain for any suitable fix.
