Stripe Payment Gateway not working.

[shadow-1995]

Impacted versions:
14.0

Steps to reproduce:
-> Setup stripe.
-> Process checkout from eCommerce shop.
-> Once payment is complete, the amount will be deducted but Odoo will show "Internal Server Error. Expected Singletone: payment.token()".

Current behavior:
Payment is not getting completed in Odoo even after successful completion on the stripe side. Instead of a Confirmation message, Internal Server Error is shown to customers.

Expected behavior:
A confirmation message should be rendered.
