Swagger metadata stopped working on a path after 0.10.1

[p-j]

Hi, we are using swagger-tools on a project and will updating it from 0.10.1 to 0.10.3 some test of ours started failing.

A quick diagnostic shows this: 0.10.1

Here is the route definition:

/**
 * @swagger
 * /files/{fileId}/-/*:
 *   get:
 *     tags:
 *       - file
 *     description: Returns file based on ID
 *     summary: Returns transformed file by ID
 *     produces:
 *       - image/jpeg
 *       - image/png
 *     parameters:
 *       - $ref: '#/parameters/fileId'
 *     responses:
 *       '200':
 *         description: the transformed file
 *       '401':
 *         $ref: '#/responses/Unauthorized'
 *       '404':
 *         $ref: '#/responses/NotFound'
 *       default:
 *         $ref: '#/responses/Unknown'
 */
router
  .route('/files/:fileId/-/*')
  .all(swaggerValidator())
  .get((req, res, next) => {
    const transformPath = req.path.replace(/\/files\/\d+/i, '')
    return res.redirect(helpers.urls.files.transform(req.fetched_file.id, transformPath))
  })

Should we change something for the middleware to continue working properly ?

Thanks

I'll have to look into it. Thanks for the report.
