~~Seems like zone-flags.ts is not part of the compilation, is zone-flags another entrypoint? Most likely this file needs to be added in the files section of your tsconfig.app.json~~

Edit: most likely in polyfills.ts you have an import with an extension. Ex: import './zone-flags.ts'. Removing the extension should solve the issue.

@rtpHarry, I actually update the comment, as the root cause seems to be an import with a .ts extension.
