Obfuscation is a nice approach to increase app security.
However it should still be possible for application developers and maintainers to identify what is causing an issue.
I have recently stumbled across two specific cases (there's certainly more), where errors could be more clear.
1. WebUI: "User '***' attempted to execute runtime operation 'R89JsA23F0qjdyi6/N/CKA' but does not have the required permissions.
for such a case there should be an easy way to find out which operation this is
2. MendixRuntimeException: Unable to find objects for guids: [43628621393362040]
If I'm not mistaken, the guid also encodes the entity type. It would help if that can be found in the log message.
Good idea. I'm struggling right now with the same error, and I'm not yet able to find the issue.
