I am new to odoo.  I have a custom payment module that I am testing on Odoo 18.  
I am able to configure and add the module properly.  When I add  a product to the cart, immediately, I get the following error.
The following modules are needed by other modules but have not been defined, they may not be present in the correct asset bundle:
- web.core
- payment.checkout_form
- payment.manage_form
 How do I overcome this challenge?
