TeamInbox and Desk Integration is Broken

TeamInbox and Desk Integration is Broken

I use the TI -> Desk integration a lot. 
Today, it broke, again.

When I go to create a Ticket from TI, an error message on a red background is shown "oops something went wrong".
Checking the developers console on my browser, there are many 500 errors relating to Zoho scripts.

I've tested from the Zoho One interface, desk.zoho.com directy and an incognito browser - all with the same results. 

Given we use this function regularly, it would be nice it just worked.
