Null check operator used on a null value error #68
Description
Hello,
I'm using UML diagram generation through GitHub Actions, and I've encountered the following error after modifying an object recently:

I'm using @JsonSerializable() in my model. Could this be causing the issue? I couldn't find any similar issues, so I'm creating this to inquire about the problem. Thank you for your assistance.
