    Disabling verbose error messages

    One thing we would like to do in our application is disable verbose error messages (i.e. stack traces) in responses to the UI from the server. What is the recommended way of doing this?

    To cover both "normal" DSRequest exceptions (like a failed database connection, for example) and more esoteric things like your use case, you would need to set two flags in your server.properties file:
    Code:
    servlet.sendStackTraceToClient: false
    exception.returns.stacktrace: false
