title: Unity Leap Motion Error Message "INPUT AXIS NOT SET UP"
body: <p>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:</p>
  
  <pre><code>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.InteractionXRController:fixedUpdateGraspButtonState(Boolean) (at Assets/LeapMotion/Modules/InteractionEngine/Scripts/InteractionXRController.cs:733)
  Leap.Unity.Interaction.InteractionXRController:fixedUpdateGraspingState() (at Assets/LeapMotion/Modules/InteractionEngine/Scripts/InteractionXRController.cs:706)
  Leap.Unity.Interaction.InteractionController:fixedUpdateGrasping() (at Assets/LeapMotion/Modules/InteractionEngine/Scripts/InteractionController.cs:1783)
  Leap.Unity.Interaction.InteractionController:Leap.Unity.Interaction.IInternalInteractionController.FixedUpdateController() (at Assets/LeapMotion/Modules/InteractionEngine/Scripts/InteractionController.cs:259)
  Leap.Unity.Interaction.InteractionManager:fixedUpdateInteractionControllers() (at Assets/LeapMotion/Modules/InteractionEngine/Scripts/InteractionManager.cs:372)
  Leap.Unity.Interaction.InteractionManager:FixedUpdate() (at Assets/LeapMotion/Modules/InteractionEngine/Scripts/InteractionManager.cs:299)
  </code></pre>
  
  <p>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.</p>
