Bug #100488
Updated by Christian Kuhn about 1 year ago
sysext/frontend/Classes/Middleware/StaticRouteResolver.php return new Response('Invalid route', 404, ['Content-Type' => 'text/plain']); This triggers a warning in Stream __construct() fopen(). For a basic fix, fix see #100487, headers might be a topic at other places, too. #100487 There are some further places in core that should be checked. Grep for 'new Response' and check factory usages as well.
