Hey @rahul88787, we are not able to reproduce this issue on a stock sandbox Solidus app on the v4.3 branch. Do you happen to have any customizations to the admin zones controller, the Spree::Zone model or a custom permission set applied to the user you are testing with?

Based on the stacktrace you have provided, it looks like the first argument to the paginate method is an Integer instead of the expected scope which should an ActiveRecord relation. The controller that sets the @zones would be a good place to start debugging this issue https://github.com/solidusio/solidus/blob/v4.3/backend/app/controllers/spree/admin/zones_controller.rb#L18
