Laravel 5.8 Eloquent不会在firstOrCreate上引用值

Question

Laravel 5.8新手。从api接收json格式的数据，将其转换为数组，然后尝试将其保存在数据库中。 firstOrCreate返回一个SQL错误，原因是一个字段中有逗号，而Eloquent没有引用这些值。 这样做

$order = Connector::firstOrCreate($connector);

$ connector数组的字段如下：

'description' => 'bla bla, bla bla, bla. Bla bla bla, bla'

是否有一种方法可以使雄辩的自动报价值（即.env文件中的值）？

php artisan tinker，然后

DB::connection()->getPdo();

返回：
