When checking right hand side of testReflect1:
When checking an application of function Reflect.getJust:
        Type mismatch between
                IsJust (Just x1) (Type of ItIsJust)
        and
                IsJust (prove (getProof x)) (Expected type)
        
        Specifically:
                Type mismatch between
                        Just x
                and
                        Nothing
