laravel terminable middleware gets called before returning response

Question

I use postman to query my laravel API and the terminate method in my middleware gets called before postman receives the result:

Route

 Route::any('/lookup', 'LookupController@lookup')->name('lookup')->middleware(\App\Http\Middleware\LogRequest::class);

Middleware

namespace App\Http\Middleware;

use Closure;


class LogRequest
{
    public function handle($request, Closure $next)
    {
        return $next($request);
    }

    public function terminate($request, $response)
    {
        sleep(10);
    }
}

The response arrives 10 seconds earlier when I remove the sleep(10); So I am sure that the server waits for terminate to finish before actually returning the response.

You need to have FastCGI for this to work, the fastcgi_finish_request() function must be available. I have the same problem with Laravel Sail

Running terminable middleware requires PHP’s fastcgi_finish_request() function, which closes the connection to the client while keeping the PHP worker available to finish the request (i.e., execute the code in your terminate() method).
