Answer 1

AdminverifyUnverify request page is declared in module so it is throwing error. Please define a component in a single place either in app.module.ts or adminverifyUnverify.module.ts.

remove it from app.module.ts if not opening it as a modal controller.

AOT compiler means [ production build ] not allowed any duplicate component to be declared in multiple places.
