Bug Report

See the repro below

1. Minimal reproduce step (Required)

schema ParentObject:
    child: ChildObject = {} # If you remove the `= {}`, then this works.

schema ChildObject:
    labels: {str:str}
    check:
        len(labels) > 0



output = ParentObject{
    child: {
        labels = {"app": "myapp", "env": "prod"}
    }
}

2. What did you expect to see? (Required)

The above should succeed since labels have len > 0

3. What did you see instead (Required)

failed the check

4. What is your KCL components version? (Required)

kcl version
0.11.2-darwin-arm64
