AST generation omits strings in C# and python

[publiosilva]

I encountered an issue when generating the Abstract Syntax Tree (AST) for the following C# and Python code snippets. The expected string values "hdfs:///" and "/" do not appear in the generated AST. Instead, the AST contains empty strings.

public class TestURIHandlerService
{
    [Fact]
    public void TestGetAuthorityWithScheme5()
    {
        var uriService = new URIHandlerService();
        // ...
        Assert.Equal("hdfs:///", uri.ToString());
        // ...
        Assert.Equal("/", uri.ToString());
    }
}

class TestURIHandlerService:
    def test_get_authority_with_scheme_5(self):
        uri_service = URIHandlerService()
        # ...
        assert uri.to_string() == "hdfs:///"
        # ...
        assert uri.to_string() == "/"
