Hi All,

I created a new website in the Odoo 18 community and installed Demo Payment Provider.
I also added a donation button on the home page.

I'm getting the below error while going to the checkout page by the donation button.



RPC_ERROR

Odoo Server Error

Occured on localhost:8069 on 2024-11-25 07:24:28 GMT

Traceback (most recent call last):

TypeError: PaymentPortal.donation_transaction() missing 4 required positional arguments: 'amount', 'currency_id', 'partner_id', and 'access_token'

The above server error caused the following client error:

RPC_ERROR: Odoo Server Error

    RPC_ERROR

        at XMLHttpRequest.<anonymous> (http://localhost:8069/web/assets/1/0b4cdbc/web.assets_frontend_lazy.min.js:4459:13)

what configuration did I miss here?
