Cloud Function deploy fails for Firestore-triggered function

[dominoFire]

[REQUIRED] Environment info

firebase-tools: 12.4.7

Platform: Windows

[REQUIRED] Test case

When I try to deploy a triggered Python, 2nd-gen cloud function, it fails with a database not found error.

[REQUIRED] Steps to reproduce

1. Create a function in your main.py:

@firestore_fn.on_document_created(document='a/{aId}/b/{bId}')
def do_magic(event: Event[DocumentSnapshot]) -> None:
    """
    Do magic
    """


    return None

2. Run firebase deploy on the function.

[REQUIRED] Expected behavior

Deploys succeeds.

[REQUIRED] Actual behavior

Deploy fails with the following message:

firebase-debug.log

Please help me diagnosing this issue. I'm blocked on writing trigger cloud functions and I don't want to default to HTTPs functions.

This issue also happens in firebase-tools 12.5.4

Hi @dominoFire, thanks for reaching out and for providing a detailed report. I tried to reproduce the behavior you mentioned, but I encountered no errors when trying to deploy the code snippet you provided.

One thing I noticed is that in your debug logs, it makes a request to GET http://127.0.0.1:8080/v1/projects/<project_id>/databases/(default). I tried comparing this to my debug logs, and mine shows GET https://firestore.googleapis.com/v1/projects/<project_id>/databases/(default).

Could you provide additional information such as your firebase.json file or if you’re setting any environment variables during/before deploying? Please remove any PII (personal identifiable information) before sharing the file.

Specifically, could you check that the FIRESTORE_EMULATOR_HOST and FIRESTORE_URL environment vairables are not set? Looking through the provided debug logs, it seems like one of them must be set & that is causing your requests to go to the wrong host.

Getting this now as well after upgrading from a Firestore v1 trigger to v2

Hey @dominoFire. We need more information to resolve this issue but there hasn't been an update in 7 weekdays. I'm marking the issue as stale and if there are no new updates in the next 3 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

I was getting the same error and it was fixed after unsetting @joehan's environment variables:

vscode ➜ /workspaces/functions (main) $ export FIRESTORE_EMULATOR_HOST=
vscode ➜ /workspaces/functions (main) $ firebase deploy --only functions:handle_dataset_created

It seems that this is a bug in the Firebase CLI as using the emulators shouldn't interfere with deploying.

Yeah, somehow I added the envvars. I haven't tested yet without the envvars, but this seems to be the error root cause. Thanks all!
