Setting up catalog mode as challenge in data security does not work correctly for insert and update transactions.
When setting up a write rule and catalog mode as challenge, the server does not send a 401 error for insert and update transactions. Instead, it sends a 200 with a "InvalidParameterValue" exception code. As for the delete transaction it works.
EDIT: I have a machine running version 2.7.6 and it correctly sends a 401 on update and insert. I am not sure on which version this bug was introduced though.
Thanks in advance!
