Right now if I save a ZTester and it is missing either a function call or a result validation, I get the following error (for ZImplementation, this happens if I leave the code/composition block empty):
{ "type": "error", "text": "ZError of type Z502" }
This should be handled:
- inline
- with a user-friendly error message
- and prevent actually saving to the backend
