Biometrics for my 12-year old daughter

I received a biometrics appointment notice for my 12-year old daugther, which surprised me since I never filled out G-325 for her associated with her I-485. Is it necessary for her to have the biometrics appointment?

Also her passport expired, which i have not renewed, Is that going to create any issues if she bring it to the appointment using it as ID?

Thank you very much!
