Error: Typed Property Must Not be Accessed Before Initialisation

[binhluong2012]

Hello,
I have issue with this error when try to set relationship #[BelongsTo(Subject::class, 'subject')] on Course model.
When I query Course::with('subject')->query()..
it's showing error "Typed Property Must Not be Accessed Before Initialisation "
Not sure how to fix it.

Tables:
courses : id, name, subject_id
subjects: id, name

Thank you.

Can you please share:
1 - A repo with the setup to reproduce the error.
2 - A PR with a failing test case.

It's going to be easier to check and fix the issue that way.
