Player error : Unable to report media inventory: Call to undefined method stdClass::save()

Hi,

I have 2 xibo player that have been up and running for a few weeks now, and I don’t know why but since yesterday, they return an error in the logs :

{
“logId”: 91140,
“runNo”: “b97389f”,
“logDate”: “2019-07-09 11:00:09”,
“channel”: “PLAYER”,
“page”: “XFA:FileManager”,
“function”: “POST”,
“message”: “Unable to report media inventory: Call to undefined method stdClass::save()”,
“displayId”: 3,
“type”: “ERROR”,
“display”: “sauna_scr2”,
“buttons”: []
},

Obviously I tried restarting my players (which are all DSDevices) but nothing changed…

I had to manually remove and reconnect all the displays, for now it’s okay with only 2 players.
The problem is that we’ll get about 60 players so we can’t do that for each of them whenever I have this error :confused:
