Since upgrading to Odoo 16, the models account.aged.payable and account.aged.receivable have been removed. I assume they have been replaced by  account.aged.payable.report.handler and  account.aged.receivable.report.handler. 

However, these models are empty and thus I can't fetch their data through xmlrpc calls. Is there something I can do to implement/activate these models? 

Is there another way to get aged payables/receivables through xmlrpc on Odoo 16?
