Is it possible to use @Parameter in a REST controller?

I'm trying to use @Parameter for a path parameter in a @RestController, but it ignores the parameter.

Note: All works well if I use @PathVariable instead (commented). However, @PathVariable does not produce the OpenAPI yaml file with all properties like "description", "references", etc, that the springdoc-openapi-maven-plugin produces automatically.

Is it possible to use @Parameter in a REST controller?

Here's my code:

@RequestMapping("/channels")  @RestController  public class ChannelRESTController {      @PostMapping("{channelId}/connect")    @Operation(summary = "Initiates a session to a channel", tags = { "session" })    @ResponseBody    ResponseEntity<?> connect( //        @Parameter(name = "channelId", in = ParameterIn.PATH,                    required = true, description = "The channel id") String channelId,        // @PathVariable(required = true) String channelId,        @Parameter(description = "Credentials' username") String username,        @Parameter(description = "Credentials' password") String password    ) {      System.out.println(          "Starting channel #" + channelId); // displays null :(      return ...    }
