RequestTimeout: Your socket connection to the server was not read from or written to within the timeout period. Idle connections will be closed.

Now I have pinned point the issue on 2.68.0 <=2.67.0 have no problems.

Further investigation:

The release change on 2.68.0 is:

feature: S3: Switches S3 to use signatureVersion “v4” by default. To continue using signatureVersion “v2”, set the signatureVersion: “v2” option in the S3 service client configuration. Presigned URLs will continue using “v2” by default.

Setting signatureVersion to v2 solve this problem: const s3 = new AWS.S3({signatureVersion: 'v2'});

The followings don’t work: const s3 = new AWS.S3(); => RequestTimeout: Your socket connection to the server was not read from or written to within the timeout period. Idle connections will be closed. const s3 = new AWS.S3({signatureVersion:'v4'); => RequestTimeout: Your socket connection to the server was not read from or written to within the timeout period. Idle connections will be closed. const s3 = new AWS.S3({signatureVersion:'v3'); => AccessDenied: Access Denied

I don’t have time to debug this, but I got the error as well. I uploaded a file from a website to my server (Node) using Ajax, and then uploaded it from my serverto S3 with code looking like this:

var stream = fs.createReadStream(pathToFile)

s3.putObject({
    Bucket: bucketName,
    Key: key,
    Body: stream
}, function(err, data){ /* Do stuff... */ })

The funny thing is that it always fails for the first Ajax request I send, but it works for all that comes after. I don’t know if this is a bug in the AWS SDK or the package multer (with express) I use to receive the uploaded file on my server (although I receive the file perfectly well as far as I can tell; it’s saved on my server).

However, when I change my code to:

fs.readFile(pathToFile, function(err, data){
    if(err){
        // Handle fail...
    }else{
        s3.putObject({
            Bucket: bucketName,
            Key: key,
            Body: data
        }, function(err, data){ /* Do stuff... */ })
    }
})

It works for all my Ajax request.

I might have done a mistake somewhere (I’m not an experience Node programmer), but hopefully this will help someone.
