如何解决API 平台自定义过滤器返回只有一个元素的数组
如果我发出一个普通请求，它会返回它应有的所有内容，但使用我的自定义过滤器，它只返回数组的第一个元素。
它应该返回的对象：

}
],"hydra:totalItems": 1,它正在返回的对象：
{
"@id": "/api/user_cars/425","userCarSpecificationValue": "Adaptives Kurvenlicht"
}
],"url": "/images/7.jpg"
}
]
}
],对我来说这很奇怪，因为如果我使用一个普通的 API 过滤器来过滤我的汽车，它会返回所有内容，但我的自定义过滤器只返回第一个对象。
