NullReferenceException in SteamVR_Action_Vibration

[Gotcab]

I tried disabling haptics when there is a button hint on the controller by settings Haptic Flash on ControllerButtonHints.cs to None instead of \actions\default\out\Haptic but it triggers a NullReferenceException in the Execute method of SteamVR_Action_Vibration.cs at line 49. It is the SourceMap that becomes null if I set Haptic Flash to None. Is it normal and/or is it the correct way of disabling haptics on button hints?

Got same error when i tried to teleport in simulation mode.
I ain't got any solution during bug trace. Null error sent from lower level API.
SteamVR_Action_Vibration.cs : 202
OpenVR.Input.TriggerHapticVibrationAction(...

Workaround : Disabling Hand.cs -> TriggerHapticPulse functions or SteamVR_Action_Vibration.cs -> Execute function makes Teleport.cs work again. (Don't use this workaround if you need haptic feedback)
Or check for simulation-VR mode. I just modified hand.cs for handType. [Fallback camera is in any mode, hands are in Left-Right hand mode].
This error apeared after latest update of steamVR.

Edit:
I see new problems in SteamVR_Input_Sources enum related scripts.
Also, Teleport.cs:895 and Teleport.cs:897 have got rightHand and leftHand property access without checking null or smth. In simulation mode, it throws null reference when transfering objects under TeleportPlayer function.

This is not the correct way to disable the haptics. Unfortunately we don't have a built in way of ignoring attempts at triggering null actions. You'll need to remove the call to trigger haptic as described above.
