[keycloak-user] Error message display

Hi, I am trying to create and display my own error messages in keycloak. In this case an error occurred in an inherited method from the UserModelDelegate. Currently the only error message I have been able to display is "Error! An unexpected server error has occurred". This isn't very helpful for our users. This is a screenshot of a successful operation: https://i.imgur.com/z9dMvxG.png This is a screenshot of a unsuccessful operation: https://i.imgur.com/LN89Qti.png It would be nice if I could display "Error! The maximum length of Description is 20 characters". Any help would be appreciated! Sincerely, Frank van Veen
