Sounds pretty reasonable for me, so fix will entail just in proper exception. Maybe it worth to show warning that says that's no data region configured and it's not possible to create LOCAL cache?

We have an erroneous use case when client tries to create LOCAL cache,
by default it does not initiates default data region. So client gets

I think it should be a lazy data region initialization on client. Do you
have any concerns about this approach or other proposals?
