I am trying to create a document with a link to Firestore with NodeJS v8.6.0. Like this
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 })
Although ref is a DocumentReference , it gives a result
Error: The "data" argument is not a valid document. The input feature is deeper than 20 levels or contains a loop.
Is there any way to do this in the NodeJS SDK (Admin)?
In addition, the package used in the code,
"firebase-admin": "^5.4.1"
and
console.log(ref)
exits
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', contributors: [Array], main: './src/index.js', files: [Array], repository: 'googleapis/nodejs-firestore', keywords: [Array], dependencies: [Object], devDependencies: [Object], scripts: [Object], license: 'Apache-2.0', engines: [Object], types: './types/firestore.d.ts' }, projectId: 'MY_PROJECT', projectIdRequired: true, Promise: [Function: Promise], grpcMetadata: Metadata { _internal_repr: [Object] }, maxRetries: undefined, userAgent: 'gcloud-node-firestore/0.8.1', activeServiceMap_: Map {}, protos: {}, _preferTransactions: false, _lastSuccessfulRequest: null, 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)' } }
and full error message
