Great work on the node! I created one for halo a while ago but haven't had time to keep up with it, so I wanted to try out others. When I tried to use the Update Ticket action to change the Client, Site and User the ability is missing.
Use Case: An email comes in from our voicemail system, it has the number in the email so we parse that out and then want to update the ticket to assign it to the correct user and company but can not with the current node.
