Custom: Roku-Card and Volume

Configuration Frontend
1

I have a Roku card that I am trying to customize to include power, and volume for an LG Webos TV. The Roku functions work fine but I cant seem to get the Webos functions to work. Extra keys not allowed @ data[“command”]. The webos integation works fine with the lg-tv-control card.

I’ve been fighting this for a couple hours so any help would be appreciated.

Is that last “data:” line supposed to be there? I don’t use the card but your other commands and the cards examples don’t have “data:” above “command: POWER_ON”
