Error in generating sales invoice via REST Api

Hi Team,

We are facing problems in generating Sales Invoice using REST Api after the ERPNext 7 upgrade.

The data that we were sending is same. But the method is breaking and not generating the invoice.

Can you guys help us get around this problem? It is frustrating how the same thing doesnt go through after the upgrade. It takes time to study the API that you provided. Now after the upgrade, same thing doesnt work.

Input JSON that we are providing is -

{

The error we are getting is as below -

Seems like you have not mentioned account in the Payment Modes table.
