Error: Unexpected end of form at Multipart._final

[seveun]

using express with firebase on serverless function

app.ts =>

`import express from 'express';
import bluebird from 'bluebird';
import cors from 'cors';
import passport from 'passport';
import bodyParser from 'body-parser';
import fileUpload from 'express-fileupload';
import router from './routes';
import session from './config/Session';
import * as auth from './auth';

(global.Promise as unknown as typeof bluebird) = bluebird;

const app = express();
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
app.use(fileUpload());
app.use(cors());
app.use(session);
app.use(router);
app.use(passport.initialize());
app.use(passport.session());
auth.init();

export default app;`

error => Error: Unexpected end of form at Multipart._final

my request is very simple :

export const patch = async (accessToken: string, body?: User, file?: any) => {
let formData
try {
if (file) {
formData = new FormData()
formData.append('file', file)
}
const { data } = await axios.patch(URL, formData || body, {
headers: {
Authorization: Bearer ${accessToken},
},
})
return data
} catch (err) {
return console.log(err)
}
}

Just ran into this issue as well with gcp cloud functions. mscdex/busboy#296 (comment) mentions a solution which I can confirm works in my tests.

@dedayoa having the same issue in local env with the gcp cloud function. Don't understand how the mscdex/busboy#296 (comment) helps since express-fileupload does not exposes to my knowledge the busboy object. Can you go into more details on how you solved your issue?

[dedayoa]

@hugoroussel I was indicating that replacing req.pipe with busyboy.end(req.rawBody) in

express-fileupload/lib/processMultipart.js

Line 184 in 98028e9

req.pipe(busboy);

got things working...but by no means the solution.
I switched to cloud run instead.

Same error. FYI I rolled back to 1.3.1 and it worked https://github.com/richardgirges/express-fileupload/releases

Whats the work around? Im just using this on local machine.

I recently got the same issue. It happened when I started using the Node.js cluster package to gain performance. It only happens when I try to upload binary files like PDF, MP4, etc... Reverting to a previous version of express-fileupload doesn't change anything for me... Anyone have any ideas?
