Sending compressed text over Amazon SQS from PHP to NodeJS

I seem to be stuck at sending the compressed messages from PHP to NodeJS over Amazon SQS.

Over on the PHP side I have:

$SQS->sendMessage(Array(
    'QueueUrl'    => $queueUrl,
    'MessageBody' => 'article',
    'MessageAttributes' => Array(
        'json' => Array(
            'BinaryValue' => bzcompress(json_encode(Array('type'=>'article','data'=>$vijest))),
            'DataType' => 'Binary'
        )
    )
));

NOTE 1: I also tried putting compressed data directly in the message, but the library gave me an error with some invalid byte data

On the Node side, I have:

body = decodeBzip(message.MessageAttributes.json.BinaryValue);

Where message is from sqs.receiveMessage() call and that part works since it worked for raw (uncompressed messages)

What I am getting is TypeError: improper format

I also tried using:

PHP - NODE

gzcompress() - zlib.inflateraw()

gzdeflate() - zlib.inflate()

gzencode() - zlib.gunzip()

And each of those pairs gave me their version of the same error (essentially, input data is wrong)

Given all that I started to suspect that an error is somewhere in message transmission

What am I doing wrong?

EDIT 1: It seems that the error is somewhere in transmission, since bin2hex() in php and .toString('hex') in Node return totally different values. It seems that Amazon SQS API in PHP transfers BinaryAttribute using base64 but Node fails to decode it. I managed to partially decode it by turning off automatic conversion in amazon aws config file and then manually decoding base64 in node but it still was not able to decode it.

EDIT 2: I managed to accomplish the same thing by using base64_encode() on the php side, and sending the base64 as a messageBody (not using MessageAttributes). On the node side I used new Buffer(messageBody,'base64') and then decodeBzip on that. It all works but I would still like to know why MessageAttribute is not working as it should. Current base64 adds overhead and I like to use the services as they are intended, not by work arounds.
