Hi. I get 422 error when trying to update DATETIME service item fields. Here is what I do: get timestamp as a string, use parse date activity to covert it to DATETIME and use the result as an update value in update service item activity. Looks pretty straightforward, but I get "Unprocessible entry" error every time. String parsing is successful, other fields in the same SI can be updated fine. Any suggestions? Thank you in advance.
