Question:
MongoDB-Cygnus Persistence

Description:
Using a sensor device (LWM2M) to receive context for historic persistence, all services run using docker-compose. I added Cygnus and set-up all docker-compose definitions. Checking up with Mongodb, device table not created, here the only db have:
$mongo

show dbs
admin 0.000GB
local 0.000GB
lwm2miotagent 0.000GB
orion-smartgondor 0.000GB
sthsmartgondor 0.000GB
use sthsmartgondor
switched to db sthsmartgondor
show collections
sth/gardensraspiSensorTV:DeviceDevice.aggr

I expect to see sth/gardensraspiSensorTV:Device_Device for device table, but not created.

I am not sure if the IDAS agent is actually receiving data from device, or if received may not be forwarded to Orion. Can someone please help how I can achive my goal, below are the IDAS agent and Orion logs please:

Looking like measures sent above, but nothing with mongodb. Also don'e understand the "DEVICEGROUPNOT_FOUND","message":"Couldn\t find device group","code":404} error. I would appreciate step-by-step process, please.
