Hello,
My problem is that I get a null reference exception: Object reference not set to an instance of an object
with the VuforiaBehaviour.Instance.World.GetTrackedObserverBehaviours() method.
Is it possible to check if it will not return null ? If yes, how ?
I've checked the Vuforia Documentation but I didn't found anything...
Vuforia version : 10.1.4
Unity version : 2019.4.15f1

Hello!
I'm getting the same error. I use Unity 2020.3.3f1.
The error is: Object reference not set to an instance of an object
with the VuforiaBehaviour.Instance.World.GetTrackedObserverBehaviours() method.
I also tried checking if it is null with: if (VuforiaBehaviour.Instance.World.GetTrackedObserverBehaviours() != null) but now I'm getting the error on that line.
Vuforia Engine is recommended to be used on Unity 2020.3 or above. I suggest upgrading to see if that fixes the issue.
Kind regards,
