#3508 [Core feature] Improve error message when using promises like regular python values Issue created by cosmicBboy Motivation: Why do you think this is important? New flytekit users will often try to manipulate promises expecting them to be regular python values. This throws off the user experience, so error messages need to be absolutely clear when doing so. Goal: What should the final outcome look like, ideally? The error message should provide a clear explanation as to why promises can only be operated on in specific circumstances.
