AWS file upload with loopback: Failed to create a multipart upload on S3

Question

Trying to upload multiple image files to AWS using loopback-component-storage

Here are the methods :

 Game.add = function(ctx,options,cb)
        {
               var status = ctx.req.query.status,
                defaultLangCode = ctx.req.query.defaultLangCode,
                nameEn = ctx.req.query.nameEn;

            var rec = new Object();
            rec.parentHouseId = houseId;
            rec.status = status;
            rec.defaultLangCode = defaultLangCode;
            rec.nameEn = nameEn;

            if(!options) options = {forceIframeTransport : true};
            ctx.req.params.container = 'common';
            Game.app.models.container.upload(ctx.req,ctx.result,options,function (err,fileObj) {
                if(err) {
                    cb(err);
                } else {
                    var fileInfo = fileObj.files.file[0];
                    console.log(fileInfo);
                }
            });
        };

AND

Game.remoteMethod(
        'add',
        {
            http:{path: '/add', verb: 'post', status: 200, errorStatus: 400},
            accepts: [
                { arg: 'ctx', type: 'object', http: { source:'context' } },
                { arg: 'options', type: 'object', http:{ source: 'query'} }
            ],
            returns: {
                arg: 'fileObject', type: 'object', root: true
            }
        }
    );

I am trying to upload two image files there. Posting data/image produces this error twice:

Second one is of-course different.

I tried using empty options object without luck.

Any kind of advice is welcome. Thanks in advance.

Tried working with different key/key id , same result. And how do I get the uploaded file's url? That of-course after I can successfully upload images :p

Are you sure your AWS key is correct? Can you upload using another client like postman? — Ebrahim Pasbani
Yes, keys are correct , if i input a wrong key this ---> "The request signature we calculated does not match the signature you provided. Check your key and signing method." is the error. — Shafayat Alam

Try enabling permission for the user in s3 bucket (permission)policy. Have you assigned a role to instance where you are running the code? (If using EC2 as your workstation)

This should have been a comment. But, unfortunately i donot have privileges to comment.
