求助，Laravel 重新接管 dingoApi 错误

因为在项目上线后要屏蔽sql方面的报错，所有按网上教的我让laravel重新接管的错误处理
我在app/Providers/AppServiceProvider 的boot 方法里加上了

// 将所有的 Exception 全部交给 App\Exceptions\Handler 来处理\
app('api.exception')->register(function (\Exception $exception) {\
    $request = Request::capture();\
    return app('App\Exceptions\Handler')->render($request, $exception);\
});

然后修改 app/Exceptions/Handle 中的 render 方法

public function render($request, Exception $exception)\
{
    $class = get_class($exception);
    if ((!env('API_DEBUG'))
        && in_array($class, self::SHIELD_ERR)) {
        return [
            'status_code' => 500,
            'message' => '服务异常',
            'data' => []
        ];
    }
}
// 屏蔽报错列表\
const SHIELD_ERR = [
    'Illuminate\Database\QueryException'
];

上线后再日志里看到这个报错

Call to a member function send() on null {"exception":"[object] (Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): Call to a member function send() on null at /www/wwwroot/MeijietuWebApi/public/index.php:58)
[stacktrace]

"}

目前没发现会有什么影响，但还是想修好，就是看不懂
