Curl error thrown for http DELETE to /session/xxxx

[ElGabbu]

I am using panther with chromedriver. I use it in a Symfony command to scrape a webpage.

$default_arguments = [
    "--headless",
    "--window-size=1280,1024",
    "--disable-gpu",
    "--no-sandbox",
    "--disable-dev-shm-usage",
];

$arguments = array_merge($default_arguments, $arguments);

$client = PantherClient::createChromeClient(null, $arguments , $options);

At the termination of the command (or even if I force cancel the command mid way) I am getting this error:

In WebDriverCurlException.php line 20:
                                                                                   
  [Facebook\WebDriver\Exception\Internal\WebDriverCurlException]                   
  Curl error thrown for http DELETE to /session/f2c85b0b97dcff0c666368402bab27ec   
                                                                                   
  Failed to connect to 127.0.0.1 port 9515 after 0 ms: Couldn't connect to server  

Any suggestion of why this happens? It would seem like the chromedriver api listening on port 9515 shutdown before that DELETE endpoint is called. But I m not sure why.
