Post Method with Guzzle doesn't work / Laravel 5 - laravel

Question

I want to execute a scheduled task with laravel, which make a post with a single param.
I already checked with Postman my POST, so, I just have to hit myurl.com with param ID=188888 for instance. I get it working with postman.
So, first, I'm making the Laravel command : check:time, which just performs the post, and then, once I get it working, I will schedule it.
Thing is it appears commands is doing nothing, and I have no error logs.
So, really, it is not so easy to debug it...
Here is my Command Code:
class CheckTime extends Command
{
protected $signature = 'check:time {empId}';
protected $description = 'Check your time';
public function handle()
{
$client = new Client;
$numEmp = $this->argument('empId');
$response = $client->post('http://example.com/endpoint.php', ['ID' => $numEmp]);
var_dump($response);
}
}
When I print $response, I get:
class GuzzleHttp\Psr7\Response#495 (6) {
private $reasonPhrase =>
string(2) "OK"
private $statusCode =>
int(200)
private $headers =>
array(6) {
'date' =>
array(1) {
[0] =>
string(29) "Wed, 01 Jun 2016 00:17:52 GMT"
}
'server' =>
array(1) {
[0] =>
string(22) "Apache/2.2.3 (Red Hat)"
}
'x-powered-by' =>
array(1) {
[0] =>
string(10) "PHP/5.3.15"
}
'content-length' =>
array(1) {
[0] =>
string(3) "146"
}
'connection' =>
array(1) {
[0] =>
string(5) "close"
}
'content-type' =>
array(1) {
[0] =>
string(24) "text/html; charset=UTF-8"
}
}
private $headerLines =>
array(6) {
'Date' =>
array(1) {
[0] =>
string(29) "Wed, 01 Jun 2016 00:17:52 GMT"
}
'Server' =>
array(1) {
[0] =>
string(22) "Apache/2.2.3 (Red Hat)"
}
'X-Powered-By' =>
array(1) {
[0] =>
string(10) "PHP/5.3.15"
}
'Content-Length' =>
array(1) {
[0] =>
string(3) "146"
}
'Connection' =>
array(1) {
[0] =>
string(5) "close"
}
'Content-Type' =>
array(1) {
[0] =>
string(24) "text/html; charset=UTF-8"
}
}
private $protocol =>
string(3) "1.1"
private $stream =>
class GuzzleHttp\Psr7\Stream#493 (7) {
private $stream =>
resource(311) of type (stream)
private $size =>
NULL
private $seekable =>
bool(true)
private $readable =>
bool(true)
private $writable =>
bool(true)
private $uri =>
string(10) "php://temp"
private $customMetadata =>
array(0) {
}
}
}
I checked that $numEmp is OK, also, I printed $response and everything seems to be fine
As I said, I also execute the post with Postman, and it works, so, I don't really understand what's going on...
Any idea??

As #Denis Mysenko wisely advised, I tried:
$response->getBody()->getContents()
and found out that my post was getting a SQL error message.
Solution: to pass form parameters with guzzle, you have to pass it like that:
response = $client->post('http://example.com/endpoint.php', [
'form_params' => [
'ID' => $empId,
...
]
]);
