I'm currently doing my first VR project with Leap Motion, HTC Vive and Unity. When I create a new project and add the LeapRig, everything is just fine, but after adding the Interaction Manager as a child of LeapRig, I get the following error message, which gets repeated multiple times a second:
INPUT AXIS NOT SET UP. Go to your Input Manager and add a definition for on the 9th Joystick Axis.
UnityEngine.Debug:LogError(Object)

Leap.Unity.Interaction.InteractionManager:FixedUpdate() (at Assets/LeapMotion/Modules/InteractionEngine/Scripts/InteractionManager.cs:299)
Has anyone an idea why this happens and how to fix it? I already worked with the interaction manager, but suddenly this error message occured. I can run my program just fine too, but the error bothers me anyway and makes it difficult to use the console properly.

From the Interaction Engine docs:
If you intend to use the Interaction Engine with Oculus Touch or Vive controllers, you'll need to configure your project's input settings before you'll be able to use the controllers to grasp objects. Input settings are project settings that cannot be changed by imported packages, which is why we can't configure these input settings for you. You can skip this section if you are only interested in using Leap hands with the Interaction Engine.
Go to your Input Manager (Edit -> Project Settings -> Input) and set up the joystick axes you'd like to use for left-hand and right-hand grasps. (Controller triggers are still referred to as 'joysticks' in Unity's parlance.) Then make sure each InteractionXRController has its grasping axis set to the corresponding axis you set up. The default prefabs for left and right InteractionXRControllers will look for axes named LeftXRTriggerAxis and RightXRTriggerAxis, respectively.
Helpful diagrams and axis labels can be found in Unity's documentation.
