Issues getting REST endpoints to work with child data source configurations

[pontiusmatt]

I am trying to get REST endpoints exposed through a single DAB instance that has child configurations for multiple database connections. When I do this per the documentation, the entities defined in the configuration in the child configs end up not setting up correctly for rest endpoints even if i define the methods they should get. The logs do not seem to be super helpful, it looks like it sets up correctly, but when I go to the swagger endpoint to inspect the endpoints the entity shows, but with no methods under it.

I am wondering if I am doing something not supported here, or if anyone out there has this functionality working?
