i am trying to capture a picture of a rendered site with Browsershot:

#[Route('/create-img-from-html', name:'create-img-from-html')]
    public function createImageFromHTML()
    {
        Browsershot::url('https://localhost:8000/test')->save('playerImage.png');
        
        ...
    }

#[Route('/test', name:'test')]
    public function test()
    {
        return $this->render('img_temp/player_template.html.twig');
    }

Problem is, that the built-in webserver seems to struggle with multiple simultaneous requests/processes, as described in this github post, even though thats laravel, but i think the problem might be the same.

The above works perfectly fine, if i switch the local url for something like ‘www.github.com’. It just doesn’t work with localhost-urls.

In the linked post, someone mentioned that you have to change the environment variable PHP_CLI_SERVER_WORKERS to something >1 to allow for multiple simultaneous processes/requests but i don’t know how to do that for the symfony webserver, because i dont use docker, like the people in the post, and i really dont find anything in the config that seems to be the right place to set this.

Can anyone help?

PS: I am using PHP 8.1 and Symfony 6.3, if that is relevant.
