View CRM Info button not working

View CRM Info button not working

I have my integration with ZOHO CRM set up, accounts and contacts get imported but for some reason when I click the View CRM button on a ticket I get the following error message.

API call cannot be completed as the Criteria parameter contains empty field name

Please help! Without seeing previous info about customers in an easy way, this system is very cumbersome to use.
This will make me want to switch back to our previous support system.
