"Operation Not Supported" Error When Bulk Updating Invoices

Summary

Encountering an "Operation Not Supported" error while performing a bulk update to invoices?

This issue could occur when trying to update voided invoices, as the system still recognizes them as existing. This article explains why this happens and provides alternative solutions.

Description

When performing a bulk operation to update invoices (ex: to update a VAT) in Chargebee, you may come across the error: "Operation Not Supported." This typically happens when attempting to update voided invoices, as the system still considers them present but not editable.

Solution

To resolve this, you have two options:

1. Delete / void and recreate the invoice from the invoice page – This allows you to generate a new invoice with the updated details.
2. Use the Regenerate Invoice API –  The Regenerate API can help regenerate the invoices with the necessary updates.
