Reading from the response stream reached the inactivity timeout - postman

Question

trying to implement REST API oauth2.0 authentification with symfony4.
The road /oauth/v2/token works well but, i'm trying to create /api/login road that will get credentials from the request and make a Httpclient->request() to /oauth/v2/token and get the access token and return to the user.
This is my code :
public function login(Request $request)
{
//dd($request->getMethod());
$method = $request->getMethod();
$grantType = $request->query->get('grant_type');
$clientId = $request->query->get('client_id');
$secretId = $request->query->get('client_secret');
$username = $request->query->get('username');
$password = $request->query->get('password');
$path = $_SERVER['API_BASE_URL'] . 'oauth/v2/token';
$httpClient = HttpClient::create();
//dd($httpClient);
$response = $httpClient->request($method, $path, [
// these values are automatically encoded before including them in the URL
'query' => [
'grant_type' => $grantType,
'client_id' => $clientId,
'client_secret' => $secretId,
'username' => $username,
'password' => $password,
],
]);
$statusCode = $response->getStatusCode();
$contentType = $response->getHeaders()['content-type'][0];
$content = $response->getContent();
$content = $response->toArray();
return $content;
}
But i'm getting this error since and i'm unable to solve :
{"error":{"code":500,"message":"Internal Server Error","exception":[{"message":"Reading from the response stream reached the inactivity timeout.","class":"Symfony\\Component\\HttpClient\\Exception\\TransportException","trace":[{"namespace":"","short_class":"","class":"","type":"","function":"","file":"D:\\vendor\\symfony\\http-client\\Chunk\\ErrorChunk.php","line":105,"args":[]},{"namespace":"Symfony\\Component\\HttpClient\\Chunk","short_class":"ErrorChunk","class":"Symfony\\Component\\HttpClient\\Chunk\\ErrorChunk","type":"->","function":"__destruct","file":"\\vendor\\symfony\\http-client\\Response\\CurlResponse.php","line":121,"args":[]},{"namespace":"Symfony\\Component\\HttpClient\\Response","short_class":"CurlResponse","class":"Symfony\\Component\\HttpClient\\Response\\CurlResponse","type":"::","function":"Symfony\\Component\\HttpClient\\Response\\{closure}","file":"\\vendor\\symfony\\http-client\\Response\\ResponseTrait.php","line":67,"args":[["object","Symfony\\Component\\HttpClient\\Response\\CurlResponse"]]},{"namespace":"Symfony\\Component\\HttpClient\\Response","short_class":"CurlResponse","class":"Symfony\\Component\\HttpClient\\Response\\CurlResponse","type":"->","function":"getStatusCode","file":"\\src\\Controller\\RestApiController.php","line":121,"args":[]},{"namespace":"App\\Controller","short_class":"RestApiController","class":"App\\Controller\\RestApiController","type":"->","function":"login","file":"D:\\Binghana\\new\\goldwin-website\\vendor\\symfony\\http-kernel\\HttpKernel.php","line":150,"args":[["object","Symfony\\Component\\HttpFoundation\\Request"]]},{"namespace":"Symfony\\Component\\HttpKernel","short_class":"HttpKernel","class":"Symfony\\Component\\HttpKernel\\HttpKernel","type":"->","function":"handleRaw","file":"\\vendor\\symfony\\http-kernel\\HttpKernel.php","line":67,"args":[["object","Symfony\\Component\\HttpFoundation\\Request"],["integer",1]]},{"namespace":"Symfony\\Component\\HttpKernel","short_class":"HttpKernel","class":"Symfony\\Component\\HttpKernel\\HttpKernel","type":"->","function":"handle","file":"D:\\Binghana\\new\\goldwin-website\\vendor\\symfony\\http-kernel\\Kernel.php","line":198,"args":[["object","Symfony\\Component\\HttpFoundation\\Request"],["integer",1],["boolean",true]]},{"namespace":"Symfony\\Component\\HttpKernel","short_class":"Kernel","class":"Symfony\\Component\\HttpKernel\\Kernel","type":"->","function":"handle","file":"D:\\Binghana\\new\\goldwin-website\\public\\index.php","line":25,"args":[["object","Symfony\\Component\\HttpFoundation\\Request"]]}]}]}}
I have tried updating httpclient version, even using Guzzle, same error.
