Response Headers are not possible to defined

[mzielinski]

Currently, we are not able to define headers for responses.

It would be good to have such possibility, the same as we can do it for requests.

It's now possible as follows:

responses = {
    @OpenApiResponse(
        status = "400",
        content = @OpenApiContent(from = EntityDto[].class),
        headers = {
            @OpenApiParam(name = "X-Error-Message", description = "Error message", type = String.class)
        }
    )
}

You can use 6.0.1-SNAPSHOT or wait for the next stable release :)
