I can set the description, when I'm creating a ticket over the API, but updating it doesn't work:

curl -u test:test -H "Content-Type: application/json" -X PUT -d '{"helpdesk_ticket": {"description": "test"}}' https://domain.freshservice.com/helpdesk/tickets/350.json

generates HTTP Error 500.

Is the request wrong, or is updating the description generally not possible?

Best regards
