Firestore 查询 where(documentId(), 'in', array) 给我一个错误

Question

I'm trying to run a query for documents in a collection that match an array of ids (custom document ids), and I'm getting this error:

Error: The corresponding value for FieldPath.documentId() must be a string or a DocumentReference.

Here is my code:

const admin = require('firebase-admin');
const db = admin.firestore();

let ids = ['12_5', '12_6'];
db.collection('myCollection').where(admin.firestore.FieldPath.documentId(), 'in', ids).get()

The documents exist in Firestore, and I created them with custom document ids to be able to easily retrieve the exact documents I need. My Documents in Firestore

Any ideas on how I can resolve this error?

Answer 1

Remove the package-lock.json lock file then install the latest @google-cloud/firestore

Answer 2

As of Dec 2022, this now works without issue. firebase-admin@^11.2.0 defines where this way:

where(
  fieldPath: string | FieldPath,
  opStr: WhereFilterOp,
  value: any
): Query<T>;

So where will no longer require just DocumentReference or string , but instead accept a FieldPath . The OP's code will now work without errors using a recent version of firebase-admin or @google-cloud/firestore .
