How do I simulate a file upload?

[ivanguimam]

I need to simulate a file upload and return the file name.

Only that sometimes it works and sometimes it generates a mistake

dyson.js

const DYSON = require('dyson')
const PATH = require('path')

let options = {
    configDir: PATH.join(__dirname, 'out-tsc', 'mock'),
    port: 3333
}
const configs = DYSON.getConfigurations(options);
const appBefore = DYSON.createServer(options);
const appAfter = DYSON.registerServices(appBefore, options, configs)

console.log('DYSON STARTED PORT 3333')

upload.ts

const formidable = require('formidable')

module.exports = {
    path: `/company/:id/file`,
    method: 'POST',
    render: async (req:any, res:any) => {
        try {
            let url = await upload(req)
            res.status(200).send({ url })
        } catch(e) {
            res.status(500).send(e)
       }
   }
}

function upload(req:any) {
    let form = new formidable.IncomingForm()

   return new Promise((resolve, rej) => {
       form.parse(req, (err, fields, files) => {
           if (files.file) resolve(files.file.name)
           else rej(err)
       })
   })
}

error

Suggestion:
Add in package.json: express-fileupload

Add in file lib/dyson.js

const fileUpload = require('express-fileupload')
...
const installMiddleware = (app, options) => {
    ...
    app.use(fileUpload())
    ...
}
...
