It works using an interface/class and using []

  references: ref[] = [];

I just added tests to show that this works as intended, see https://github.com/deepkit/deepkit-framework/commit/373a69857410ec5cac376a61bcd63078e5d9596d. We also have templates assigned to kind=0, so I'm not sure where this error is coming from.

So, please post a full reproduction example if you still get this error in the newest version
