在Firestore（NodeJS）上的文檔中設置DocumentReference

我正嘗試使用NodeJS v8.6.0在Firestore上創建一個帶有引用的文檔。像這樣在Firestore（NodeJS）上的文檔中設置DocumentReference

const admin = require('firebase-admin') 
admin.initializeApp({ credential: MY_CREDENTIAL, databaseURL: MY_DB_URL }) 
const db = admin.firestore() 

const ref = db.doc('foo/someDoc') 
db.doc('bar/targetDoc').set({ link: ref })

雖然ref是DocumentReference，它導致

Error: Argument "data" is not a valid Document. Input object is deeper than 20 levels or contains a cycle.

反正有做它的NodeJS（管理）SDK？

另外，在該代碼中使用的包是

"firebase-admin": "^5.4.1"

和

console.log(ref)

輸出

DocumentReference { 
    _firestore: 
    Firestore { 
    makeAuthenticatedRequest: 
     { [Function: makeAuthenticatedRequest] 
     getCredentials: [Function: bound getCredentials], 
     authClient: [Object] }, 
    authClient: 
     Auth { 
     authClientPromise: null, 
     authClient: null, 
     config: [Object], 
     environment: {} }, 
    baseUrl: undefined, 
    getCredentials: [Function: bound getCredentials], 
    globalInterceptors: [], 
    interceptors: [], 
    packageJson: 
     { name: '@google-cloud/firestore', 
     version: '0.8.1', 
     author: 'Google Inc.', 
     description: 'Firestore Client Library for Node.js',

    api: { Firestore: [Object] }, 
    _referencePath: 
     ResourcePath { 
     segments: [], 
     _formattedName: undefined, 
     _projectId: 'dewpod-dev', 
     _databaseId: '(default)' }, 
    app: 
     FirebaseApp { 
     firebaseInternals_: [Object], 
     services_: [Object], 
     isDeleted_: false, 
     name_: '[DEFAULT]', 
     options_: [Object], 
     database: [Function: bound ], 
     auth: [Function: bound ], 
     messaging: [Function: bound ], 
     storage: [Function: bound ], 
     firestore: [Function: bound ], 
     INTERNAL: [Object] }, 
    INTERNAL: FirestoreInternals {} }, 
    _referencePath: 
    ResourcePath { 
    segments: [ 'orgs', 'fooOrg' ], 
    _formattedName: undefined, 
    _projectId: 'dewpod-dev', 
    _databaseId: '(default)' } }

和完整的錯誤消息是

/SOME_PATH/node_modules/@google-cloud/firestore/src/validate.js:86 
     throw new Error(message); 
     ^

@NovoLucas似乎該示例不保存任何引用。你能指出它在哪裏嗎？ –

這應該起作用，所以這可能是一個依賴性問題，使得'DocumentReference'在'set'中檢查instanceof失敗。你如何導入Firestore？你確定你只輸入一次嗎？你可以'console.log（ref）;' 另外，你正在使用哪個版本的節點？ –

@GilGilbert編輯了這篇文章。請檢查。而且，是的，我可以用NodeJS v8.6.0以最少的代碼重現它。「需要（'firebase-admin'）」一次，「admin.initializeApp」一次。 –

這是admin SDK和Firestore常規節點SDK之間的交互中的一個錯誤。

更新至@ google-cloud/firestore 0.8.2應該可以解決此問題。

您可以用npm update更新您的項目以獲得此更改。
