GetComponentInParent is returning null when the GameObject is a Prefab

Scene Management


How to reproduce:
1. Open the attached project (
2. Click on the 'test' GameObject and make sure the 'MyPrefab' field is set 'Foobar' Prefab
3. Enter Play Mode

Expected result: methods 'GetComponentInChildren', 'GetComponent', 'GetComponentInParent' return non null Components and the according messages get displayed in the Console window
Actual result: 'GetComponentInParent' returns null

Reproducible with: 2018.4.23f, 2019.3.16f1, 2020.1.0b11, 2020.2.0a12

All mentioned methods are working fine with instantiated Prefabs or regular GameObjects.

    This is incorrectly marked as a duplicate of an unrelated issue! In fact, you must pass `includeInactive=true` to get a non-null result when calling this function on an uninstantiated prefab (which is easy to unwittingly do via the `OnValidate` function, for example).

    This is very misleading. I'm traversing the prefab, and I can do a GetComponent<X>() and it works, then GetComponentInParent<X>() and it fails. Confused me for quite a while. Changing to GetComponentInParent<X>(true); works. Seems like it should be consistent. I would suggest in the prefab, that it does not require a true call unless it is actually inactive.
