(Help, Redux, ReduxDnD) - Accessing top level store from a drop target

If anyone in the community is successfully using ReactDnD with Redux, I’d like to ask for their help with this issue here:

I’ve spent a whole weekend looking up the relevant sources and I’m convinced that I’m doing it badly wrong but I don’t know what. In fact, I think there’s a bigger issue of how I’m doing react/redux in general.

Would really appreciate any help in the right direction.
