Hello,
I believe you need to provide more context on what is your setup and what you are trying to achieve.
From the log it seems that the database you are trying to use is not initialised. Are you using a different instance from the default one?
Are you using wires? If so, what is the graph and the component's configuration.
Maybe you can review all the components' configuration and see if you changed something from the default one that caused the issue.
Best regards,
Matteo
