This fix seems reasonable, but I wonder why we're getting an empty object for metadata here when in project-based schema generation we get a reference to the ObjectMeta schema, which lives in a separate file.
The main difference I see in the two code paths is that the project schema gen calls crd.ToOpenAPI rather than extracting the OpenAPI schema directly from the CRD. This helper does a bit of manipulation to improve the output. I wonder if we could/should call crd.ToOpenAPI in the CRDsToJSONSchemas path as well, to make our two schema generation methods match. @fernandezcuesta any thoughts?

Yeah makes sense, I wasn't focusing on the why as you mention. I'll see what we can do to amend it. |

Thanks for the update, @fernandezcuesta - I like the new implementation, and agree it's reasonable to also keep the empty object handling you originally added for cases where we do end up with an empty object definition for some reason.
Would it be reasonable to add a unit test that exercises the ref rewriting in CRDsToJSONSchemas? I think it's covered at a high level by the existing tests for crossplane xrd convert, but I'm not sure we're validating the ref rewriting itself there. Maybe there's a JSONSchema validator we could add to those tests?

Yep, adding some tests (a bit naïve but I guess enough to validate it) |
