        return response()->json($json, 400);
    }
    
    // Show HTTP exceptions
    if ($this->isHttpException($e)) {
        // Check if the app is installed when page is not found (or when 404 page is called),
        // to prevent any DB error when the app is not installed yet
        if (method_exists($e, 'getStatusCode')) {
            if ($e->getStatusCode() == 404) {
                if (!appIsInstalled() && $request->input('exception') != '404') {
                    return redirect(getRawBaseUrl() . '/install?exception=404');
                }
