Bench --site command missing in frappe docker custom app using castlecraft / custom_containers

unable to perform site operations such as
bench --site sitename install-app appname in the docker

Built a custom app by using castlecraft / custom_containers

everything works fine. but bench is missing --site command.

@revant_one any idea on this.

The problem was, payments app was not included in the apps.json list. Hence installation failed.
I observed that bench --site sitename install-app command wasn’t working without erpnext installed during the bench new-site.

I will post further updates if any other observation comes in between
