Payment success page error in erpnext 14

i’m using the erpnext v14 manual installation and facing this issue. After the successful payment, when redirecting to the payment success page, I’m facing this error.

After Looking into the code, I knew that in the payment_success.py file, frappe is trying to get the docname and doctype but unable to get this.

i’m getting doctype and docname as none because form_dict only contains “redirect_to” field and due to this, error is occuring here

doc = frappe.get_doc(doctype, docname)

In the documentation, the only thing mentioned is to put the keys into the braintree settings to setup payment gateway and the payment is working successfully but not building the payment_success page only due to this error.
