'content' output is missing for OpenAPI generation

As reported in Discord:

https://discord.com/channels/766016904056930325/766022847155535933/938702938321354773

See below for the report.

OpenAPI is generated by appmap-js, using the openapi command:

https://appland.com/docs/reference/cli-client.html#openapi

It crawls over all the AppMaps and reverse-engineers the OpenAPI YAML document from the observed web service calls.

Some information such as the content is reported missing. This should be populated with at least a MIME Type. Maybe the code is looking for the outdated field http_server_response.mime_type instead of http_server_response.headers?

Hey I am trying to generate swagger documentation using appmap
i was following this:

https://appland.com/docs/reference/appmap-swagger-ruby.html

for my test cases, i am using RSpec (type: request) and factory_bot

I was able to generate the swagger docs but the POST API request doesn't contain any request body

My question is do I specifically need to update the openapi_stable.yaml file to generate it correctly
or do I need to write the request spec in rswag format because curently i am doing it like this

require 'rails_helper'

RSpec.describe 'Api::V1::Users', type: :request do
  describe 'POST /api/v1/users/' do
    it 'creates a new user' do
      total_users = User.all.count
      request_body = {
        user: {
          fullname: 'New User',
          email: 'new@gmail.com',
          password: 'asdasd12ad'
        }
      }
      post api_v1_users_path, params: request_body
      expect(response).to have_http_status(201)
      expect(User.all.count).to eq(total_users + 1)
    end
  end
end

openapi: 3.0.1
info:
  title: Rails api
  version: v1.0
paths:
  "/api/v1/users":
    post:
      responses:
        '201':
          content: {}
        '422':
          content: {}
components:
  securitySchemes: {}
servers:

  variables:
    defaultHost:
      default: localhost:3000

Start at the appmap-js openapi command described in the issue and trace how observed web service responses become the generated OpenAPI YAML. Compare the use of http_server_response.mime_type with the available http_server_response.headers; done means generated response content includes at least the observed MIME type.
