title: Recieving an "errorCode: ERROR_RESOURCE_GONE" when trying to send play command
body: <p>I have been trying to figure out the sonos api over the past few days, but unfortuanetly have hit a road block. I have already gotten my tokens and room names and and favorites Id, but when I send the curl request to play a song I get the error described above.</p>
  <p>Curl Code :
  curl -X POST -H &quot;Content-Type: application/json&quot; -H &quot;Authorization: Bearer {TOKEN}&quot; &quot;https://api.ws.sonos.com/control/api/v1/groups/RINCON_48A6B88A5B14014XX:XXXXXXXXXX/favorites&quot; --data @play.json</p>
  <p>I keep the body in a .json file called play which contains the code:</p>
  <p>{
  &quot;favoriteId&quot;:2,
  &quot;playOnCompletion&quot;:true
  }</p>
  <p>I have not been able to find any documentation on this issue online, so any and all help is very appreciated.</p>
