Question:
fiware quantumleap insert into cratedb not working (schema missing)

Description:
goal
Use qunatumleap to move data into a crate_db to display later using Grafana.
what I did

follow tutorial to setup Docker images
setup opc-agent to provide data to the orion broker
setup quantumleap to move data from broker to crate_db on change
checked that a subscription is present in the contextBroker

Expected behavior
on subscription of a new item quantumleap will create a entry in a table in the crate_db to store the provided values
what actually happens
Instead of creating a entry in the Crate_db quantumleap throws a "schema not existing" fault.
The provided tutorials do not talk about setting those schema up myself, therefore I assume that quantumleap normally sets them up.
Right now I do not know why this is failing, most likely it is a configuration mistake on my side
additional information

subscription present in contextBroker:
curl -X GET \
'http://localhost:1026/v2/subscriptions/' \
-H 'fiware-service: openiot' \
-H 'fiware-servicepath: /'
