ValueError: too many values to unpack (expected 3) when using with turtlebot launch file

[tobiasduerschmid]

When I launch rosdiscover on this turtulebot launch file https://github.com/turtlebot/turtlebot/blob/3e32933c829e308600707a9f971334d13d1cbe19/turtlebot_bringup/launch/3dsensor.launch

I get this error:
