TypeError: Cannot read properties of undefined

[mbeauchemin]

Hello! I recently purchased a Polisy and installed the trial version of ST-Sonos to test it out before purchasing. The node server runs for about a day with no issues and then errors with the following stack trace. Restarting the node server is successful and it works again for about a day until it crashes again in the same manner.

Let me know if there is anything else necessary to further troubleshoot. I would like to get this functional so I can test before buying. Thank you!

So I keep restarting the node server and it keeps crashing with the same error. I enabled debug logging on the last cycle and it appears it fails right after communicating regarding my Sonos Roam. Restarting and trying again to see if it is repeating this pattern.

@simplextech any insights or suggestions for debugging? I'd really like stabilize this NS so I can actually buy it in confidence. Happy to provide the whole debug log for your review.

 

Thank you!

That is interesting.  Please do send me a private message and attach the log file to the message.  Do you have any other Sonos players besides the Roam?
