I receive this error while posting a webhook on Sales invoice submission.

TypeError: Object of type 'SalesInvoiceItem' is not JSON serializable
I use Items(table) as webhook data to send items details.
This was working fine in the previous version of erpnext.
My Current version is
ERPNext: v12.1.8 (version-12)
Frappe Framework: v12.0.18 (version-12)
Any help will be highly appreciated.
