upload image to s3 from node js

Question

I'm trying to upload a file to s3 but it not happening what I expected. I create a file-helper.js in middleware, that is looks like below

const aws = require('aws-sdk');
const multer = require('multer');
const multerS3 = require('multer-s3');

aws.config.update({
        accessKeyID:'XXXXXXXXXXXXXX',    
        SecretAccessKey:'XXXXXXXXXXXXXXXXXXXXXXXXXXX',
        region:'ap-south-1'
});

const s3 = new aws.S3();

const fileFilter = (req, file, cb) => {
    if (file.mimetype === 'image/jpeg' || file.mimetype === 'image/png') {
      cb(null, true);
    } else {
      cb(new Error('Invalid file type, only JPEG and PNG is allowed!'), false);
    }
  }

const upload = multer({
    fileFilter,
    storage: multerS3({
      s3,
      bucket: 'demo.moveies.com',
      acl: 'public-read',
      metadata: function (req, file, cb) {
        cb(null, {fieldName: file.fieldname});
      },
      key: function (req, file, cb) {
        cb(null, Date.now().toString())
      }
    })
  })

  module.exports = upload;

and my controller file like below

const upload = require('../middleware/file-helper');
const imageUpload = upload.single('image');
exports.fileUpload = async(req,res)=>{
    imageUpload(req, res, function(err, some) {
        if (err) {
          return res.status(422).send({errors: [{title: 'Image Upload Error', detail: err.message}] });
        }
        return res.json({'imageUrl': req.file.location});
      });
}

when hit the API end point it is giving error

{ "errors": [ { "title": "Image Upload Error", "detail": "Missing credentials in config" } ] }

I'm not able to figure out where I went in wrong in my code. can one help me in this situation

Troubleshoot -- Are your Config for S3 correct ? specifically the region ? — user6202450

Be sure about that. you can find your region through the amazon s3 url. — user6202450

There are typos in your config details. It should be accessKeyId not accessKeyID and secretAccessKey and not SecretAccessKey.

You have used the wrong key SecretAccessKey and accessKeyID, try changing it to secretAccessKey and accessKeyId.

aws.config.update({
    accessKeyId:'XXXXXXXXXXXXXX',    
    secretAccessKey:'XXXXXXXXXXXXXXXXXXXXXXXXXXX',
    region:'ap-south-1'
});
