Swagger not showing documentation with Koa annotations

I have a simple rest API that works with Koa and MySQL and now I want to add some swagger documentation, I have done the first part of the api-docs route works however it doesn’t seem to be able to load the options I defined.

I expect it to load the option and the annotations I defined

Thanks a lot in advance and a happy new year 😀

**login.ts**

import { verifyLogin, verifyCaptcha } from "../middlewares/login.middleware"
import LoginController from "../controller/login.controller"

const KoaRouter = require('@koa/router')

const loginRouter = new KoaRouter({
    prefix: '/login'
})


/**

 * /login:
 *    post:
 *      description: User Login
 *      responses:
 *        '200':
 *          description: Successfully login

loginRouter.post('/', verifyLogin, verifyCaptcha, LoginController.generateToken)


export default loginRouter

**swagger.ts**

const path = require('path');
const KoaRouter = require('@koa/router')
const swaggerJsdoc = require('swagger-jsdoc');
import { koaSwagger } from 'koa2-swagger-ui';

const options = {
    swaggerDefinition: {
        openapi: '3.0.0',
        info: {
          title: 'My API',
          version: '1.0.0',
          description: 'This is a sample server',
        },
    },
    apis: [path.join(__dirname, '../router/*.ts')],
};

const swaggerDocs = swaggerJsdoc(options);

const docsRouter = new KoaRouter({
    prefix: '/api'
})

docsRouter.get('/docs', koaSwagger({ routePrefix: false, swaggerOptions: { swaggerDocs } }))


export default docsRouter

This is what happens when the console prints
