Cannot read property 'length' of undefined #706

Closed jrtaaffe closed 5 years ago

jrtaaffe commented 5 years ago

I am having the following error when running the api:

(node:2766) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'length' of undefined (the full stack trace is below)

It appears that I get an error block like this for each sonos speaker in my system. I can get some data in the responses, but it is incomplete. For example, /players/kitchen/state returns volume info, but no currentTrack or nextTrack values and the playbackState is incorrect:

{"volume":11,"mute":"mute off","equalizer":{"bass":null,"treble":null,"loudness":true},"currentTrack":{"artist":"","title":"","album":"","albumArtUri":"","duration":0,"uri":"","type":"track","stationName":""},"nextTrack":{"artist":"","title":"","album":"","albumArtUri":"","duration":0,"uri":""},"trackNo":null,"elapsedTime":0,"elapsedTimeFormatted":"00:00:00","playbackState":"pause","playMode":{"repeat":"none","shuffle":"shuffle off","crossfade":"crossfade off"}}

Oh good, it isn't just me then! Same error in my logs. It was working a couple of days ago.

The data I'm getting back for all zones looks like this:

   ]
},

That's a zone that is currently playing an album from Spotify.

By the way, I have also tried re-installing, and I've tested 3 different environments (including a newly set-up raspberry pi), but they all produce the same error. Any help would be greatly appreciated! Thank you!

hdurdle commented 5 years ago

Same - I suspect Sonos has changed something. They did just release their Google Home support, maybe it has changed the nature of the data.

jishi commented 5 years ago

Which software version do you guys have on the Sonos players?

jishi commented 5 years ago

never mind, I get the same error now with the latest sonos-discovery

jishi commented 5 years ago

Was a dependency that had a breaking change (sigh..), I don't get that error anymore. An npm install should revert the dependency, but if you still have issues on latest master, wipe node_modules and do npm install again.
