Whats wrong with this code

const Openapi = require('moleculer-auto-openapi')

module.exports = {
  name: 'openapi',
  mixins: [Openapi],
  settings: {
    // all setting optional
    openapi: {
      info: {
        // about project
        description: 'Foo',
        title: 'Bar'
      },
      tags: [
        // you tags
        { name: 'auth', description: 'My custom name' }
      ],
      components: {
        // you auth
        securitySchemes: {
          myBasicAuth: {
            type: 'http',
            scheme: 'basic'
          }
        }
      }
    }
  }
}

 {
        path: '/api/openapi',
        aliases: {
          'GET /openapi.json': 'openapi.generateDocs', // swagger scheme
          'GET /ui': 'openapi.ui' // ui
        }
      },
