Angular 8 - Lazy loading modules : Error TS1323: Dynamic import is only supported when '--module' flag is 'commonjs' or 'esNext'

Question

When I updated Angular from 7 to Angular 8, getting error for lazy loading modules

I have tried the options, which are there in the angular upgradation guide

Just want to add my experience to @Tony's answer. After changing tsconfig.json it still showed an error (red underline). Only after reopening the editor (I used VSCode) did I see the red underline disappear.
