Issue

Hi there. I've noticed that AgnosticDatabase is included in several method signatures, but it doesn't seem to be used within the methods themselves. The application appears to be functioning on AIOEngine. In my project cases, I have already removed AgnosticDatabase. If it is needed in the future, I can create a pull request to reintroduce it. Could you kindly clarify if there are plans to utilize AgnosticDatabase in the future or if it will be removed from the method signatures? Thank you.

Definition of done

Remove references to the `AgnosticDatabase` when not needed in the function signatures of the backend code.

Pitfalls

Due to how deeply nested some calls are, this will break several other routes. It could take time to make sure the tests run through all of the provided routes.
