Zoho CRM - Mail Merge not working

Zoho CRM - Mail Merge not working

Hello ,

I have a flow created to send the mail merge as an attachment in an email once record is created in Zoho CRM's Contacts module.

The flow was working perfectly fine until yesterday.

But today it is showing an error in Zoho CRM's server.

Please find the attached screenshot.

Thanks
Darshil
