错误，对成员函数send（）的调用为null

Question

The font-end of my october CMS instance suddenly started giving me out the following error code:

Call to a member function send() on null

$kernel = $app->make('Illuminate\Contracts\Http\Kernel');

$response = $kernel->handle(
    $request = Illuminate\Http\Request::capture()
);

$response->send();

$kernel->terminate($request, $response);

Any Idea what could be causing it? I probably was adding a translation for another language while this happened.

I tried to find other posts about similar problems, but there seem to be so many cause for this error and I'm not a programmer. Thank you!

最可能的原因是，您使用的自定义middleware在某种情况下不会返回$next($request)或任何东西，这些东西将返回null而不是响应。
