What is app:129? You can click or tap the "error" box (or the similar "info," "debug," etc. boxes) to go to that app. The method names suggest it might be something from Groups and Scenes. If this guess is correct, what kinds of devices do you have in that group or scene? You could try just hitting "Done" in that app and see if the problem goes away after that (maybe you deleted a bulb/switch that was once part of the group?).
If it does persist and you see some connection to CoCoHue, let me know. Otherwise, I haven't seen this before and can't tell anything from these logs alone, especially without knowing what anything is from.
Is it possible that app 129, whatever it happens to be, references a device that no longer exists? Like a scene that contains a Hue light that is no longer there?
It appears that app:129 was a group of mixed bulbs/dimmers. Some attached to my Hue bridge and one connected thru the Kasa driver. All the devices in the group were still present and all working as expected. However the group was not used anymore so I simply deleted it and the error messages vanished.
