将 Parse Server 从 v3 升级到 v4 会触发错误“GraphQL：必须提供源”

Question

我在版本 3.10.x 中使用 ParseServer (https://parseplatform.org) 和附带的 GraphQL 端点。我使用 apollo-link 从我的云代码中进行一些查询，因此安装了 graphql 模块（此外还有使用 apollo-server 的 parse-server 的依赖项）。我已经指定了 GraphQL 依赖项的版本以匹配 parse-server (v14.5.8).

使用的版本

在此配置中一切正常。

我现在将 parse-server 升级到最新版本 4.3.x，并更新 graphql 以继续匹配 parse-server 使用的版本：v15 .1.0.

服务器现在在启动时崩溃并出现错误：Must define Source. Received undefined.。

所以我尝试删除 graphql 依赖项，我仍然得到错误。
我已将 graphql 降级到以前的版本 v14.5.8，但由于使用了 2 个不同的 graphql 实例，所以出现另一个错误。
我检查过跨依赖项只使用了一个版本的 GraphQL。

我检查了错误发生时加载的graphql模块：./node_modules/graphql in version v15.1.0.

有没有人知道这个错误以及修复它的方法？

如果需要更多详细信息，请询问！

谢谢，

Parse Server 由 throng 在集群中启动。

解析服务器初始化

const restAPI = new ParseServer(config)
const graphQL = new ParseGraphQLServer(restAPI, {
    graphQLPath: process.env.GRAPHQL_MOUNT || "/graphql",
    playgroundPath: "/playground",
})

// Serve the Parse API on the /parse URL prefix
app.use(process.env.PARSE_MOUNT, restAPI.app)
graphQL.applyGraphQL(app)

解析服务器配置

{
        appName: process.env.PARSE_APP_NAME,
        databaseURI: process.env.DATABASE_URI,
        databaseOptions: {
            maxTimeMS: Number(process.env.DB_QUERY_MAX_TIME) || 30000,
        },
        cloud: `${__dirname}${cloudCode}`,
        appId: process.env.PARSE_APP_ID,
        masterKey: process.env.PARSE_MASTER_KEY,
        clientKey: process.env.PARSE_CLIENT_KEY,
        javascriptKey: process.env.PARSE_JAVASCRIPT_KEY,
        restAPIKey: process.env.PARSE_REST_KEY,
        serverURL: serverURL,
        publicServerURL: serverURL,
        allowClientClassCreation: process.env.ALLOW_CLIENT_CLASS_CREATION === 'true',
        filesAdapter: new S3Adapter(
            process.env.S3_BUCKET, {
                bucketPrefix: process.env.S3_BUCKET_PREFIX,
                directAccess: true
            }),
        verifyUserEmails: false,
        emailAdapter: MailAdapter(),
        cacheAdapter: process.env.REDIS_PARSE_CACHE_URL
            ? new RedisCacheAdapter({ url: process.env.REDIS_PARSE_CACHE_URL })
            : null,
        liveQuery: {
            classNames: ["SomeClass"],
            redisURL: process.env.REDIS_LIVE_QUERIES_SERVER_URL
        },
    }

几周后，在没有进一步研究的情况下，有人建议我尝试使用 npm 而不是 yarn。所以我试过了，整个过程又恢复正常了。运行。

问题出在锁定文件中：删除后，即使用 yarn 恢复，问题也已解决。

因此，如果您遇到这种情况，请尝试删除 node_modules 文件夹和锁定文件，然后 re-run yarn 或 npm install。这应该可以解决问题。
