[REQUIRED] Version info

node:

node version : 10

firebase-functions:
3.12

firebase-tools:
8.16.2

firebase-admin:
9.3.0

[REQUIRED] Test case

Create custom token with claims
const claims = {test:"test"}; const uid = 123; admin.auth().createCustomToken(uid, claims);

delete user (this is dart code)
final currentUser = await FirebaseAuth.instance.currentUser(); await currentUser.delete();

trigger:
exports.deleteUserData = functions.auth.user().onDelete((userRecord, context) => { console.log(userRecord.customClaims); console.log(context.auth.token); });

[REQUIRED] Steps to reproduce

1. create a custom token with claims.
2. Login using the custom token.
3. After login with custom token, delete user with flutter client sdk.
4. Check function logs and see that customClaims is empty.

[REQUIRED] Expected behavior

context.auth.token
and
userRecord.customClaims

should not be undefined or empty, but contain the claims of the deleted user.

[REQUIRED] Actual behavior

email: null, emailVerified: false, displayName: null, photoURL: null, phoneNumber: null, disabled: false, providerData: [], customClaims: {}, passwordSalt: null, passwordHash: null, tokensValidAfterTime: null, uid: '10659670',

Were you able to successfully deploy your functions?

No error messages

@mortlun thank you for the feedback. Functions SDK simply unpacks the events that are sent from the Firebase Auth server on delete events, and this isn't something we can fix here in the Functions SDK.
