I've implemented a Keycloak Storage Provider plugin that communicates with a remote user store. When an error occurs, I want that to be shown in the Admin UI. For example, in the Admin UI under Users you can display a list of users. You can then show/edit a given user's attributes by clicking on the user's ID link. When an error occurs, I throw an Exception. However this just shows up as an unknown server error. Is there any way to get the Admin UI to show the message in the exception or some other way to get the UI to display the error like a Status.setError() API I may have missed?
