angular 8 webpack-bundle-analyzer looking for wrong polyfill files

No matter what I do, after building my project I keep getting the following error:

Error parsing bundle asset "<path-to-project>\polyfills-es5-es2015.e1bdcd70857e70f37509.js": no such file
events.js:174

Which is exactly right seeing that my project creates a polyfills-es5.e1bdcd70857e70f37509 file and a polyfills-es2015.25bfed26497f24d6d1d7 file.

This is in a nx workspace project that I created yesterday

After every build the file names obviously changes, but it keeps looking for a mixed es5-es2015 polyfills file.

The stats file gets created as stats-es2015.json and our package.json settings is: "bundle-report": "webpack-bundle-analyzer dist/apps/<project-name>/stats-es2015.json"

I keep getting the error with default build or production, with ivy enabled or disabled, and I eve tried to remove the es5BrowserSupport flag, hoping there will only be one polyfills file, but it is still looking for es5-es2015 file...

Try this command to see if it work for you

ng build --prod --stats-json && webpack-bundle-analyzer dist/stats.json

My tsconfig.json

    "module": "esNext",
    "target": "es5",

I can also maybe add that I think at the end of the day my solution was just to simply close all my vsCode windows.

When ever I have vsCode open I would get the polyfills-es5-es2015.<whatever>.js": no such file error, but when I close vsCode and run the exact same command it works...

I think it may have to do with having the angular ui plugin in vsCode, that has some kind of bundle tool as well that uses the same port as wba. So it actually has nothing to do for me with not finding the polygon file, but it still gives that error when the wba port is in use...

PS: I found this out when checking if that port was indeed in use on my machine, and it showed that it was in use by vsCode, so something in vsCode is using it and closing vsCode solved the error for me...
