Missing "authtype" and "authid" for "on_document_written_with_auth_context" trigger functions in emulators

[andreas-thomik]

Pretty much what the title says. The authid and authtype fields are present for all the other on_document_<...>_with_auth_context functions but are missing for on_document_written_with_auth_context

This might be an issue with the emulators themselves, if so please let me know and I'll post it to the relevant issue tracker.

Hello @andreas-thomik. Is this only reproducible with emulators?

[andreas-thomik]

Honestly not tested since #207 makes the _with_auth_context functions useless at the moment but I'll try a minimal setup later tonight and will report back.

@exaby73 I can confirm that this happens for both emulators and live functions.

Here's a minimal example to reproduce:

import logging

import firebase_functions.firestore_fn
from firebase_functions.firestore_fn import (
    AuthEvent,
    Change,
    DocumentSnapshot,
    _firestore_endpoint_handler,
    on_document_created_with_auth_context,
    on_document_written_with_auth_context,
)

logger = logging.getLogger()

def _inspect_endpoint_handler(*args, **kwargs):
    logger.warning("Args: %s", args)
    logger.warning("Kwargs: %s", kwargs)

    return _firestore_endpoint_handler(*args, **kwargs)

firebase_functions.firestore_fn._firestore_endpoint_handler = (
    _inspect_endpoint_handler
)

@on_document_written_with_auth_context(document="tests/{docId}")
def test_doc_written(event: AuthEvent[Change[DocumentSnapshot | None]]):
    return event

@on_document_created_with_auth_context(document="tests/{docId}")
def test_doc_created(event: AuthEvent[DocumentSnapshot]):
    return event

The actual parameters sent to _firestore_endpoint_handler can be seen in the logs, here's a (slightly redacted) copy of mine:

Logs for on_document_written_with_auth_context

Compare this with the logs for on_document_created_with_auth_context:

This seems to be an upstream issue. I've raised this forward. I'll get back to you soon on an update on this issue

For context, seems to be a similar issue on the Node SDK as well (https://github.com/firebase/firebase-functions/issues/1582)
