help: "zoho.invoice.update" stopped working today

Hi, I have a script that uses 

zoho.invoice.update("Invoices",organization.get("organization_id"),invoice.get("invoice_id"),fields);

and today it stopped working. Is this something with zoho? I see also info zoho.invoice.getRecords does not work. I tried with "invoices" as well, but it is the same problem.

What happened?
