const swaggerSettings = {
  apiVersion: '1.0.0',
  swaggerVersion: '1.0',
  swaggerURL: '/docs',
  swaggerJSON: '/api.json',
  swaggerUI: resolve(__dirname, 'public'),
  basePath: 'http://localhost:9001',
  apis: [
    '../user/routes.js'
  ]
};

my project tree

  swagger/
    index.js
  user/
    index.js

asap open the /api.json URL I got a ENOENT: no such file or directory, open './../operator/routes.js' on terminal
