S3 Upload

I've done everything like in your tutorial except your Ruby script. I've used node js aws-sdk:

const aws = require('aws-sdk');
var config = require('../../server/config.json');
aws.config = config.aws;

    const s3 = new aws.S3();
    const s3Params = {
      Bucket: config.aws.bucket,
      Key: instance.filename,
      Expires: 60,
      ACL: 'public-read'
    };

    s3.getSignedUrl('putObject', s3Params, (err, signedUrl) => {
      if(err){
        return next(err);
      }
      instance.uploadUrl = signedUrl;
      next();
    });

So I've got signed URL

------WebKitFormBoundarygDui83iohothuh7E--

And I've got from Amazon:

<Error><Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided. Check your key and signing method.</Message><AWSAccessKeyId>AKIAIFVWPIVVIGIONPXA</AWSAccessKeyId><StringToSign>PUT

Something wrong with your request, because when I put it with CURL:

curl -k -X PUT -T "IMG_4875.PNG.png" "https://f.workdoer.com.s3.amazonaws.com/IMG_4875.PNG.png?AWSAccessKeyId=AKIAIFVWPIVVIGIONPXA&Expires=1502381111&Signature=Af9meXlMA7qj5HYALs7LzhWaftc%3D&x-amz-acl=public-read"

It's successfully uploaded. What I'm doing wrong?

Here is my bucket policy:

    {
        "Version": "2008-10-17",
        "Statement": [
            {
                "Sid": "Allow Public Access to All Objects",
                "Effect": "Allow",
                "Principal": {
                    "AWS": "*"
                },
                "Action": [
                    "s3:DeleteObject",
                    "s3:GetObject",
                    "s3:PutObject"
                ],
                "Resource": "arn:aws:s3:::f.workdoer.com/*"
            }
        ]
    }

And cors:

    <?xml version="1.0" encoding="UTF-8"?>
    <CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <CORSRule>
        <AllowedOrigin>*</AllowedOrigin>
        <AllowedMethod>PUT</AllowedMethod>
        <AllowedMethod>POST</AllowedMethod>

        <AllowedHeader>Content-Type</AllowedHeader>
        <AllowedHeader>x-amz-acl</AllowedHeader>
        <AllowedHeader>origin</AllowedHeader>
        <AllowedHeader>accept</AllowedHeader>
    </CORSRule>
    </CORSConfiguration>

Thanks for any help.
