[Bug] Assertion Error During deep_check

[kugesan1105]

Describe the bug

When performing a deep check , the following code line causes an unexpected assertion error:

visit [-->](`?test_node);

If the line is commented out or modified to visit [-->];, deep check completes successfully. This indicates a possible issue with the visit statement when specifying the node type in deep check.

To Reproduce

node test_node {
    has value: int;
}

walker test_walker {
    can traverse with root entry {
        # visit [-->](`?test_node);          # error while deep check 
          visit   [-->];                     # working
    }

}

with entry {
    for i in range(10) {
        root ++> (next := test_node(value=i));
    }
    wlk_obj = root spawn test_walker();
    print(wlk_obj);
}
