Hello, I'm using UML diagram generation through GitHub Actions, and I've encountered the following error after modifying an object recently:

`Null check operator used on a null value

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.

I have the same problem, once I removed JsonSerializable it no longer has the problem
