The error content dialogue mentions overlapping shifts
There may be shifts that have been created manually in Provet instead of imported from Quinyx. These may be blocking Quinyx import. The solution is to leave these shifts as they are or remove them from Provet and import again from Quinyx.
The error content dialogue mentions '{"user":["Select a valid choice. That choice is not one of the available choices.","This field is required."]}'
The user may have been inactivated (archived) in Provet. Another possibility is that two users may have the same employee number in Provet.
The error content dialogue mentions '{"non_field_errors":["User not found"]}'
This is most likely due to a mismatch in the user's Provet employee number and Quinyx's badge number. Check the user's employee number in Provet.
The error content dialogue mentions "HTTPError", "ConnectionError" or "Unauthorized"
This may be because Quinyx API has IP restrictions. To fix this problem, the public IP address(es) that the HR Gateway uses should be sent to the local Quinyx support and they can whitelist the address(es). Provet support can be contacted to find the correct public IP address(es).
