Error when initializing OpenVR (try 1 / 4) recently

Hi,

I was successfully able to use your code roslaunch htc_vive_teleop_stuff vive_tf_joy_and_ps.launch few days back but today I am facing an issue all of a sudden.

Error when initializing OpenVR (try 1 / 4)

I am trying to use HTC Vive Controller in headless mode by changing the below settings for SteamVR beta.

I have enabled the null driver

"driver_null": { "enable": true,

"steamvr": { "requireHmd": false, "forcedDriver": "null", "activateMultipleDrivers": true

Does anyone have any idea why is this occurring?

Update

I changed openvr.init(openvr.VRApplication_Scene) to openvr.init(openvr.VRApplication_Other) in vive_tf_and_joy.py on line # 182 and it worked surprisingly. But I don't know the reason as openvr.init(openvr.VRApplication_Scene) was working earlier.
