GuzzleHttp give me 500 error - php

Question

I try to use GuzzleHttp with Magento to update my product catalog.
I use a pool request to get data from database and I try to post them into magento trought API
$apiUrl = 'http://xxx.xxxxx.xxx';
$middleware = new Oauth1([
'consumer_key' => '-------------------------------',
'consumer_secret' => '-------------------------------',
'token' => '-------------------------------',
'token_secret' => '-------------------------------'
]);
$stack->push($middleware);
$client = new Client();
$clientUpdate = new Client([
'base_uri' => $apiUrl,
'handler' => $stack,
'auth' => 'oauth'
]);
$mapper = new JsonMapper();
$requests = function ($total) {
$uri = 'http://10.0.0.114:15021/myservice';
for ($i = 1; $i <= $total; $i++) {
yield new Request('GET', $uri.$i);
}
};
$pool = new Pool($client, $requests(3), [
'concurrency' => 3,
'fulfilled' => function ($response, $index) {
global $clientUpdate, $mapper;
$productsArray = $mapper->mapArray(
json_decode($response->getBody($asString = TRUE)), new ArrayObject(), 'ProductGo'
);
$product = new Product();
$stock = new StockData();
foreach($productsArray as &$value){
$product->type_id = "simple";
$product->attribute_set_id = 4;
$product->sku = $value->xxxxxxxxxxxxxxx;
$product->weight = 1;
$product->name = $value->xxxxxxxx;
$product->price = $value->xxxxxxxx;
$product->status = 1;
$product->visibility =4;
$product->tax_class_id = 4;
$product->description = $value->xxxxxxx;
$product->short_description = $value->xxxxxx;
$stock->qty = $value->xxxxx;
$stock->min_qty = "0";
$stock->is_qty_decimal = 0;
$stock->is_in_stock = 1;
$product->stock_data = (object) array_filter((array) $stock);
$productIn = (object) array_filter((array) $product);
try{
$response = $clientUpdate->request('POST', '/api/rest/products', ['json' => json_encode($productIn)]);
echo $response;
}catch (RequestException $e) {
echo GuzzleHttp\Psr7\str($e->getRequest());
if ($e->hasResponse()) {
echo GuzzleHttp\Psr7\str($e->getResponse());
}
}
}
},
'rejected' => function ($reason, $index) {
echo $reason;
},
]);
// Initiate the transfers and create a promise
$promise = $pool->promise();
// Force the pool of requests to complete.
$promise->wait();
Pool request works ok. If I debug I will put a break point where I make a request but after I get ever the same error

I can't understand what's the problem, I've tried to post with postman this json as product and it works.
Any suggestions???

http://docs.guzzlephp.org/en/latest/request-options.html#jso
Summary:
The json option is used to easily upload JSON encoded data as the body
of a request. A Content-Type header of application/json will be added
if no Content-Type header is already present on the message.
Here's an example on how to set up the header on request:
$client->request('POST', $url, [
'headers' => [
'Accept' => 'application/json',
],
'body' = $body
]);
