OpenApi doc not beeing generated properly

I'm having a hard time to generate a correct Openapi documentation using swagger-maven-plugin-jakarta.

I've created a simple springboot application just to clarify:

Environment:

swagger-maven-plugin-jakarta: 2.2.28
swagger-core-jakarta: 2.2.28
swagger-annotations: 2.2.28

I have a simple API:

package com.example.demo.controller;

import static jakarta.ws.rs.core.Response.Status.CREATED;

import com.example.demo.controller.dto.RequestDto;
import com.example.demo.controller.dto.ResponseDto;
import io.swagger.v3.oas.annotations.Operation;
import io.swagger.v3.oas.annotations.media.Content;
import io.swagger.v3.oas.annotations.media.Schema;
import io.swagger.v3.oas.annotations.responses.ApiResponse;
import io.swagger.v3.oas.annotations.tags.Tag;
import jakarta.validation.Valid;
import jakarta.validation.constraints.NotNull;
import jakarta.ws.rs.POST;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.core.MediaType;
import jakarta.ws.rs.core.Response;

@Path("/v1/auth")
@Tag(name = "Simple API", description = "Operations related to a simple API")
public class SimpleController {

  @POST
  @Path("/create")
  @Operation(summary = "Create",
      description = "Create a simple entity",
      responses = {
          @ApiResponse(responseCode = "201",
              description = "Entity created",
              content = @Content(
                  mediaType = MediaType.APPLICATION_JSON,
                  schema = @Schema(implementation = ResponseDto.class))),
          @ApiResponse(responseCode = "500", description = "Internal server error")
      })
  public Response create(@NotNull @Valid final RequestDto dto) {

    try {
      final var responseDto = new ResponseDto();
      return Response.status(CREATED)
          .entity(responseDto)
          .build();
    } catch (Exception e) {
      return Response.serverError().build();
    }
  }

}

Then I have two simple dtos:

package com.example.demo.controller.dto;

import io.swagger.v3.oas.annotations.media.Schema;
import io.swagger.v3.oas.annotations.media.Schema.RequiredMode;
import jakarta.validation.constraints.NotBlank;

@Schema(name = "Request")
public class RequestDto {

  @Schema(minLength = 1, maxLength = 10, requiredMode = RequiredMode.REQUIRED,
      name = "id", description = "Id of entity to be created", example = "34786293")
  @NotBlank(message = "Id cannot be blank")
  private String id;
}```

```java
package com.example.demo.controller.dto;

import com.fasterxml.jackson.annotation.JsonFormat;
import io.swagger.v3.oas.annotations.media.Schema;
import io.swagger.v3.oas.annotations.media.Schema.RequiredMode;
import java.time.ZonedDateTime;

@Schema(name = "Response")
public class ResponseDto {

  @Schema(minLength = 1, maxLength = 10, requiredMode = RequiredMode.REQUIRED,
      name = "id", description = "Id of entity to be created", example = "34786293")
  private String id;

  @Schema(format = "date-time", requiredMode = RequiredMode.REQUIRED,
      description = "Date in ISO 8601 format of YYYY-MM-DDThh:mm:ss.SSSZ in UTC",
      name = "created_at", example = "2021-05-26T15:36:19.000Z")
  @JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSX")
  private ZonedDateTime createdAt;
}

And after I compile the project, this is the Openapi documentation I get:

openapi: 3.0.1
tags:
- name: Simple API
  description: Operations related to a simple API
paths:
  /v1/auth/create:
    post:
      tags:
      - Simple API
      summary: Create
      description: Create a simple entity
      operationId: create
      requestBody:
        content:
          '*/*':
            schema:
              $ref: "#/components/schemas/Request"
        required: true
      responses:
        "201":
          description: Entity created
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/Response"
        "500":
          description: Internal server error
components:
  schemas:
    Response:
      required:
      - created_at
      type: object
      properties:
        created_at:
          type: string
          description: Date in ISO 8601 format of YYYY-MM-DDThh:mm:ss.SSSZ in UTC
          format: date-time
          example: 2021-05-26T15:36:19Z
    Request:
      type: object

Note that the request schema is missing and the response is missing a field.

Am I missing something?

The demo project I created can be found here https://github.com/tiagofvalerio/demo

Start with the linked demo project and reproduce generation using SimpleController, RequestDto, and ResponseDto with swagger-maven-plugin-jakarta 2.2.28. Compare the generated OpenAPI YAML with the DTO annotations, focusing on the missing Request fields and Response.id. Done means both schemas retain the annotated fields and constraints shown in the example.
