filename tmp-1-1616611601149 instead of filename on the host pc

code: const fileUpload = require("express-fileupload"); app.use(fileUpload({ limits: { fileSize: 1024 1024 1024 // 1 GB }, abortOnLimit: true, safeFileNames: true, preserveExtension: 8, //debug: true, useTempFiles : true, tempFileDir : '/tmp/', uriDecodeFileNames : true, defParamCharset: 'utf-8' }));

app.post("/updateFile", (req, res) => { if (!req.files) { return res.status(400).send("No files were uploaded."); }

const file = req.files.userAppFile;
console.log('upload : ' + JSON.stringify(file))
const path = '/var/volatile/tmp/' + file.name;

file.mv(path, (err) => {
  if (err) {
    return res.status(500).send(err);
  }
  return res.send({ status: "success", path: path });
});

});

Log:

upload : {"name":"tmp-1-1616611601149","data":{"type":"Buffer","data":[]},"size":341712,"tempFilePath":"/tmp/tmp-2-1616611601150","truncated":false,"md5":"cdf49126018bb6e5f43f0e9e87ba7319"}

I tried using the example provided with package using postman with a file "option.ko". The size is correct and file contents are correct.

Hi,

That can happens if client didn't send a file name or server was not able to get it some how. When the name empty or it is not a string, mw set it to random file name, see code below:

if (!fileName || typeof fileName !== 'string') return getTempFilename();
