The error is gone, it still works:-),
but still the issue when Google home mini media source is becoming None, the first time ONLY the volume change is ignored, the second time the trigger comes the volume is changing well.
After Media source None, we see at the first trigger the message media source is set to Hubitat (17u55min10sec) , in that case the volume to 80 procent is ignored but the message is played (not visible in de log's), the second time (17u55min24sec) everything is working well.
