Warning: Entry point 'ngx-linkifyjs' contains deep imports into '/Users/rahulkhunt/Documents/angular-upgrade/flocksy-new-app-2.0/node_modules/linkifyjs/plugins/hashtag', '/Users/rahulkhunt/Documents/angular-upgrade/flocksy-new-app-2.0/node_modules/linkifyjs/plugins/mention', '/Users/rahulkhunt/Documents/angular-upgrade/flocksy-new-app-2.0/node_modules/linkifyjs/string'. This is probably not a problem, but may cause the compilation of entry points to be out of order.

Getting above message while building with Angular v9.1.12
