[REQUIRED] Step 2: Describe your environment

• Operating System version: MacOS 10.14.5
• Firebase SDK version: 7.2.1
• Library version: firebase-tools v'7.2.1' & firebase-admin v'8.3.0' & firebase-functions v'3.2.0'
• Firebase Product: admin & firestore (auth, database, storage, etc)

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

• I was used firebase-tools v'7.0.0' & firebase-admin v'7.0.0' & firebase-functions v'2.3.0', then can use method 'getCollections' of DocumentReference.

• But I was upgrade version firebase-tools v'7.2.1' & firebase-admin v'8.3.0' & firebase-functions v'3.2.0', then I can't use this method and occur this error.

Did you deprecated this method or not? I still see The documentation at here for this method 'https://firebase.google.com/docs/firestore/query-data/get-data#list_subcollections_of_a_document'

Relevant Code:

await documentRef.getCollections()

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Oh, I saw you was changed method name 'listCollections', but you don't mention this method is deprecated :(, Ref: (https://googleapis.dev/nodejs/firestore/latest/DocumentReference.html#listCollections)

This is one of the breaking changes that went out with Firestore 2.0.0 and Admin 8.0.0. But the documentation still shows the old method it seems. @schmidt-sebastian FYA.

[schmidt-sebastian]

It looks like we forgot to update our docs. Thanks for catching that!

@samtstern Can you update the code snippets on https://firebase.google.com/docs/firestore/query-data/get-data#list_subcollections_of_a_document to use listCollections() for Java and Node?

getCollections was deprecated as of v0.18.0.

I've created an internal bug to track the documentation update. Closing this since there's no action items for this repo.
