fiware quantumleap insert into cratedb not working (schema missing)


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

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

edits

  • added docker compose file

Solution

  • after changing the database to a more recent version (for example crate-db:3.1.2) the data arrives at the database nicely
