Can't compile expression that return objects with mixed properties types

Question

Hi, I am playing with playground to scope what is achievable or not with CEL and to spot what is valid CEL syntax or not.

Further Information

I try to implement an expression that return an object base on name This example is for simplicity purpose only. input: person: name: 'sam'

expression KO person.name == 'sam' ? { 'status': 'adult', 'age': 39} : { 'status': 'unknown', 'age': 0} is failing to compile

but as soon as I change "age" and "adult" properties to string expression OKperson.name == 'sam' ? { "status": "adult", "age": "39"} : { "status": "adult", "age": "0"} it compiles and is evaluated

and even inconsistent object shape return is fine as long as all properties does have the same type expression OK2 person.name == 'sam' ? { 'status': 'adult', 'age': '39'} : { 'status': 'unknown'}

Why is there such constraint?

I dont know if the issue is specific to cel-playground or to the underlying used implementation

Thank for your time or for that online tool, it is so helpful to ramp-up 👍
