Amazon S3 copyObject - File not showing in bucket

Question

I am trying to copy an object using the Amazon s3 copyObject () method.

Below is the code:

$copied = $s3->copyObject(array(
                            'Bucket' => $this->bucket,
                            'CopySource' => urlencode($this->bucket .'/'.$source_file),
                            'Key' => $this->dir.$jduid.'/'.$new_file
                            ));

This method works fine. If I print the result of copyObject, I get:

Guzzle\Service\Resource\Model Object
(
[structure:protected] => 
[data:protected] => Array
    (
        [LastModified] => 2016-10-26T07:32:34.373Z
        [ETag] => "08fa3106a8b7839b803f4ddf65b56919"
        [Expiration] => 
        [CopySourceVersionId] => 
        [ServerSideEncryption] => 
        [SSECustomerAlgorithm] => 
        [SSECustomerKeyMD5] => 
        [SSEKMSKeyId] => 
        [RequestCharged] => 
        [RequestId] => c0a80b5b:1558b420117:3e7c6:9a9
    )

)

But I can not find the new copied file in the bucket. Any suggestion.
