Flutter Webview Error acquiring assertion; Client is missing required entitlement;

Question

For both flutter_webview_plugin.dart' and webview_flutter.dart'

I am getting the following error when I got to certain websites. No errors if I go to youtube or google. How can I find out what required entitlement it is missing?
