having problem using 'livingroom'

[bradanlane]

for some reason, Alexa commands which act on my zone called 'livingroom' are failing.

I have confirmed that 'livingroom' (no space) is in the ROOMS list and is the name of the Sonos unit.

Example1 :
Utterance: "Alexa tell sonos set current room to livingroom"
Result URL: /undefined/linein/undefined
this one is totally baffling

Example 2:
Utterance: "Alexa tell sonos play artist james taylor in livingroom"
Result URL: /room/musicsearch/apple/artist:James%20Taylor
this one fails to determine the correct room and uses 'room' as the sonos device name

Using other sonos device names such as 'office' or 'kitchen' works.

I do have ADVANCED_MODE true
