hmmmm.
ok, so looking at your error...
... it happens in lgtv-volume.js at line 19
This is the code on the repo - node-red-contrib-lgtv/nodes/lgtv-volume.js at 16583f19ea2aeccaa9a43599da25966a99d2aa79 · hobbyquaker/node-red-contrib-lgtv · GitHub
Looking at the code on that line ...
if (!err && res && res && res.changed.indexOf('volume') !== -1) {
node.send({payload: res.volume});
}
... I suspect the dev meant to write ...
if (!err && res && res.changed && res.changed.indexOf('volume') !== -1) {
node.send({payload: res.volume});
}
Try that in file /home/pi/.node-red/node_modules/node-red-contrib-lgtv/nodes/lgtv-volume.js then restart node-red
