AppDaemon does not start after a reboot

Installation Home Assistant OS
1

AppDaemin was running fine - Apps, HA Dashboard! After a reboot (without any config change), I receive following error message

Error: Asked to process document index 0 but there are only 0 document(s)
20:13:42 main [ERRO] Asked to process document index 0 but there are only 0 document(s)

I have no idea, what the problem is. Has somebody a hint for me? Any feed back welcome - thanks!

Same issue, i am very new to home assistant about 4 days. But figuring this out. Did you have any lucky to get appdaemon to start?
