We upgraded our environment into latest 8.4 R06 and with the service module, we have quite serious problems.
When ticket comes in and our service people tries to assign tickeet to active user, program gives an error message and then it stucks. Error message is Bad ajax return status 500. In log file i can see a lot of AjaxApp: Integrity check for data failed. -1.
Another problem is, that when service people tries to reply to the ticket, it does not fech emails into to field autoomatically. And when they type e-mail address into the to field, it does not find the match.
It makes it more complex, that from time to time both previously mentioned problems works. After a while, it is possible to assign ticket, and when it works, reply fetches also email addresses to and cc fields.
How can i fix the proble. Our service is stuck right now.
