As you can see Wait For (Res1) Complete (Result As Object) returns the wrapper instead of the inner object.

If I change it to Result As Map all works well.

This is not a bug. The type in the Complete event must be of the correct type in the case of wrapper objects. Object will not work here. You will get a similar error with CallSub.

The compiler doesn't know that you want to unwrap the object and it passes the object as-is.
