Content & configuration

Example Swagger/OpenAPI definition:

{"openapi":"3.1.0","info":{"title":"FastAPI","description":"This is a sample FastAPI application.","version":"1.0.0"},"paths":{"/items/":{"get":{"summary":"Read Items","description":"Retrieve items.","operationId":"read_items_items__get","responses":{"200":{"description":"Successful Response","content":{"application/json":{"schema":{"$ref":"#/components/schemas/Item"}}}}}}}},"components":{"schemas":{"Item":{"properties":{"name":{"type":"string","title":"Name"},"description":{"type":"integer","title":"Description"},"nested_item":{"$ref":"#/components/schemas/NestedItem"}},"type":"object","required":["name","description","nested_item"],"title":"Item"},"NestedItem":{"properties":{"name":{"type":"string","title":"Name"},"description":{"type":"integer","title":"Description"}},"type":"object","required":["name","description"],"title":"NestedItem"}}}}

Describe the bug you're encountering

In the previous version of swagger with openapi 3.0.2, we used to see the reference of Nested Schema with the name of that nested schema. In the current version(5.*) with openapi 3.1.0 I can see object instead of Nested Schema reference

Expected behavior

It should show nested schema reference like below. Its working with OpenAPI 3.0.2

No source files or tests are named. Start by loading the supplied OpenAPI 3.1.0 definition in Swagger UI 5 and compare nested $ref rendering with the reported OpenAPI 3.0.2 behavior; done means NestedItem is displayed by name rather than as object in the response schema.
