Unexpected end of form

[caiodigioia]

Hey guys! Why am I getting this error? I found this code in a YouTube tutorial (https://www.youtube.com/watch?v=04QoJx7r_XQ&lc=UgzNYMVDuSx_ip2J56l4AaABAg), published 2 years ago. I think something may have changed. Can someone help me please?

Here is my code:

Servico.routes.js: (I've noticed that the console.log('Try') does not appear in the console, so I guess there is a problem to make the try, but I don't know what is the problem)

const express = require('express');
const router = express.Router();
const Busboy = require('busboy')
const aws = require("../services/aws")
const Salao = require('../models/salao');
const Arquivo = require('../models/arquivo');
const Servico = require('../models/servico');

router.post('/', async (req, res) => {

        let busboy = Busboy({ headers: req.headers})
        console.log('Cheguei aqui')

        busboy.on('finish', async () => {

            try {
                console.log('Try')
                const { salaoId, servico } = req.body;
                let errors = [];
                let arquivos = [];

                if (req.files && Object.keys(req.files).length > 0) {

                    for (let key of Object.keys(req.files)) {
                        const file = req.files[key];

                        // blablabla.jpg
                        const nameParts = file.name.split('.'); // [blablabla, jpg] 
                        const fileName = `${new Date().getTime()}.${nameParts[nameParts.length - 1]}`
                        const path = `servicos/${salaoId}/${fileName}`

                        const response = await aws.uploadToS3(file, path)

                        if (response.error) {
                            errors.push({ error: true, message: response.message})
                        } else {
                            arquivos.push(path)
                        }
                    }
                }

                if (errors.length > 0) {
                    res.json(errors[0]);
                    return false
                }

                // Criar serviço
                let jsonServico = JSON.parse(servico);
                const servicoCadastrado = await Servico(jsonServico).save();

                // Criar arquivo
                arquivos = arquivos.map(arquivo => ({
                    referenciaId: servicoCadastrado._id,
                    model: 'Servico',
                    caminho: arquivo,
                }));

                await Arquivo.insertMany(arquivo)

                res.json({ servico: servicoCadastrado, arquivos })

            } catch (err) {
                res.json({ error: true, message: err.message })
            }
        })
        req.pipe(busboy);
});

module.exports = router;

index.js:

const express = require('express');
const app = express();
const morgan = require('morgan');
const cors = require('cors');
const busboy = require('connect-busboy')
const busboyBodyParser = require('busboy-body-parser')

app.use(express.json());
app.use(busboy())

The problem is apparently you're trying to use busboy three different times (via connect-busboy, busboy-body-parser, and then explicitly in your route handler). Once anything (busboy or otherwise) has consumed the entire request body, nothing else can consume it because there is no more data. That is why you're seeing the error.

Thanks so much, @mscdex ! I solved the error.
