We have several versions of the questionnaire and some assignments have been made for the older version. We now want to archive those old assignments, so that assignments would be removed and would not appear on the interviewer tables.
When we try to archive assignments we get error 405. Could someone help how to overcome this or/and how to properly remove old assignments and make a new one with the new version of the questionnaire?
Error message: Request failed with error code 405.
Same error appear if assignment is closed or not.
Thank you very much beforehand.
