Unwanted "result" Value in @RequestMapping `produces` Attribute Generated by OpenAPI Generator

I'm using the OpenAPI Generator plugin for server stub generation based on a Swagger 2.0 specification. I’ve encountered an issue where the generated code contains an unwanted "result" value in the produces attribute of the @RequestMapping annotation in the Spring Boot server stub.

Issue:

In the generated code, I have the following @RequestMapping annotation:

@RequestMapping(
    method = RequestMethod.POST,
    value = "/users", 
    produces = { "application/json", "result" },
    consumes = { "application/json" }
)

As you can see, the produces attribute includes "result" as a media type, which should not be there. The produces attribute is intended to specify valid media types (like "application/json", "application/xml", etc.), but "result" seems to have been mistakenly added.

Example Swagger Spec (relevant part):

responses:
  200:
    description: Successful response
    schema:
      type: object
      properties:
        result:
          type: object
          properties:
            someData:
              type: string

What I've Tried:

1. Reviewed the Swagger Spec: I've checked my Swagger 2.0 spec, and there's no reason for "result" to be in the produces field. The spec only defines response data, not media types like "result".
2. Checked the Generated Code: The produces field in the generated @RequestMapping annotation is incorrectly including "result".
3. Looked at the OpenAPI Generator Templates: I haven’t customized the templates yet, but I’m wondering if this might be necessary.

My Question:

• Why is OpenAPI Generator adding "result" as a value in the produces attribute of the @RequestMapping annotation? Could it be related to the way the response body is defined in the Swagger 2.0 spec?
• How can I fix this issue so that only the correct media types (like "application/json") appear in the produces field, and "result" is not added?
• Should I customize the OpenAPI Generator templates to prevent this from happening, and if so, how would I do that?

Any guidance or solutions would be greatly appreciated!

No source file, generator version, command, or test is named. Start by reproducing the Spring Boot server stub from the minimal Swagger 2.0 response shown, then inspect the Spring server templates and response media-type calculation. Done means the generated @RequestMapping contains only declared media types and a regression test covers the result property case.
