Currently, the editor for 3.0.0 does not show semantic errors, so it’s not covered by it. Technically, it’s not an error, it’s just meaningless (and we show it as a warning).

However, the Swagger.io UI seems to get confused. In the example below, with the yellow "$ref" commented out, the UI will show the two distinct paths as expected. However, when I make the $ref active (attempting to reuse the /sources/{uid} definition as "least common denominator", and extend it with additional (non-conflicting) parameter from /source/{neighbors}_{uid}), the result in the UI is rather unexpected: The first path suddenly has the parameter from the SECOND path? openopenapi: "3.0.0" info: version: 1.0.0 title: Test servers: - url: http://api.test.com/v1 paths: /sources/{uid}: get: summary: Retrieve one individual Source object. parameters: - $ref: "#/components/parameters/Path_uid" responses: default: description: Default Response /sources/{neighbor}_{uid}: # $ref: "#/paths/~1sources~1{uid}" get: summary: Retrieve the neighbor of one individual Source object. parameters: - $ref: "#/components/parameters/Path_neighbor" responses: '200': # OK description: Test Response components: parameters: Path_uid: name: uid in: path description: The unique ID of the object to be accessed, or "first" or "last". required: true schema: oneOf: - type: integer - type: string enum: [first, last] Path_neighbor: name: neighbor in: path description: The direction, either "before" or "after", relative to the unique ID. required: true schema: type: string enum: [before,after] -- You received this message because you are subscribed to the Google Groups "Swagger" group.
