Zoho Finance Bug: Custom Buttons no longer work within Zoho Finance Module. Only response is "An Error Occurred"

Zoho Finance Bug: Custom Buttons no longer work within Zoho Finance Module. Only response is "An Error Occurred"

This is a major bug that started happening on Monday for us. I was onto support for 2 hours and they confirmed the bug.

This has crippled our operation as we run a ton of automation based on these custom buttons.

To replicate scenario
- Open the CRM Finance > Sales Orders module
- Click on any Custom button you have created.

Expected Outcome
- Your custom function should run and return your expected result

Actual Outcome
- You just get a popup message saying "An Error ocurred. Please try again later"
