In your first post youâve posted your schema. In it you show to have no relationship from Bio to person. In order for makeAugmentedSchema to know how to create the correct relationship you need to include the relationship on both the person and bio type. With a correct in and out direction for the relationship. This does not create a separate relationship just ensures that itâs mapped correctly.
Try that and see if it fixes your mutation. If it doesnât then holpefully someone else feels like helping you.
