Laravel Lighthouse 错误：响应不成功：收到状态码 500

Question

我将 laravel lighthouse 用于 graphql，在 lighthouse playground 中编写 graphql 查询时遇到此错误：

ServerError：响应不成功：收到状态码 500

bundle.esm.js:69 POST http://127.0.1.4/api500（内部服务器错误）

我在打开灯塔游乐场页面时收到此错误，我什至没有机会编写查询。

这是我的灯塔配置文件，我只是将route 部分更改为api 以及这部分'enable' => env('LIGHTHOUSE_CACHE_ENABLE', false)：

<?php

return [
    'route' => [
        'uri' => '/api',

    ],
    'defer' => [
        'max_nested_fields' => 0,
        'max_execution_ms' => 0,
    ],
];

这是我的 CORS 配置文件，我只是将 paths 部分更改为 api：

<?php

return [
    'paths' => ['api/*'],
    'allowed_methods' => ['*'],
    'allowed_origins' => ['*'],
    'allowed_origins_patterns' => [],
    'allowed_headers' => ['*'],
    'exposed_headers' => [],
    'max_age' => 0,
    'supports_credentials' => false,
];

这是 graphql 的架构文件：

"A date string with format `Y-m-d`, e.g. `2011-05-23`."
scalar Date @scalar(class: "Nuwave\\Lighthouse\\Schema\\Types\\Scalars\\Date")

"A datetime string with format `Y-m-d H:i:s`, e.g. `2018-05-23 13:43:32`."
scalar DateTime @scalar(class: "Nuwave\\Lighthouse\\Schema\\Types\\Scalars\\DateTime")

"A datetime and timezone string in ISO 8601 format `Y-m-dTH:i:sO`, e.g. `2020-04-20T13:53:12+02:00`."
scalar DateTimeTz @scalar(class: "Nuwave\\Lighthouse\\Schema\\Types\\Scalars\\DateTimeTz")

type Query {
    fields(input: ListInput @spread): [Field]
    field(id: ID! @eq): Field @find(model: "App\\Field")
}

type Mutation {
    createField(
        name_en: String! @rules(apply: ["required"])
        name_fa: String
        description: String
        img_url: String
    ): Field @create(model: "App\\Field")

    updateField(
        id: ID! @rules(apply: ["required", "int"])
        name_en: String @rules(apply: ["required"])
        name_fa: String
        description: String
        img_url: String
    ): Field @update(model: "App\\Field")

    deleteField(
        id: ID! @rules(apply: ["required", "int"])
    ): Field @delete(model: "App\\Field")
}

type Field {
    id: ID!
    name_en: String!
    name_fa: String!
    description: String!
    img_url: String!
    created_at: DateTime!
    updated_at: DateTime!

    subFields: [SubField] @hasMany
}

input ListInput {
    page: Int @rules(apply: ["int"])
    limit: Int @rules(apply: ["int"])
    q: String @rules(apply: ["string", "max:191"])
}

我真的不知道问题是什么。希望你能帮我解决这个问题。

在 CORS 配置文件中替换以下代码：

'paths' => ['api/*', 'graphql'],
'allowed_methods' => ['*'],
'allowed_origins' => ['*'],
'allowed_origins_patterns' => [],
'allowed_headers' => ['*'],
'exposed_headers' => false,
'max_age' => false,
'supports_credentials' => false,
