Code:

var multer  = require('multer');

var storage = multer.diskStorage({
    destination: function (req, file, cb) {
        cb(null, './photos')
    },
    filename: function (req, file, cb) {
        cb(null, file.fieldname + '-' + Date.now())
    }
})

var upload = multer({ storage: storage }).any()

app.post('/admin/uploadpicture', upload, function(req, res) {
    res.send('Test');
});

Not able to understand where i am missing, kindly suggest anything. Thank you in advance.

Increase the field data limit using the limits option:

multer({
  limits: { fieldSize: 2 * 1024 * 1024 }
})

Solution 2:[2]

you can use upload.array('field') to upload as many files as you want.

Solution 3:[3]

if after adding the limits to multer you are still seeing this issue, it is likely because you are attempting to upload the same image multiple times and it is having trouble over riding the previous image. i've uploaded a new pic
