I have a plugin that exposes a resource configuration. When I clicked to see the configuration, I only saw a message in the UI about not being able to retrieve it. In the log, I saw a message (not a full stack trace) about not being able to find a class on the plugin (i.e. there was an error loading the configuration). This error should be displayed in the UI so the user knows what happened and the stack trace should be available in the logs.
