CloudTasksClient causing error when instantiated in Firebase Function's onDocumentCreated

Question

I have whittled my firebase functions index.ts down to the code below and I am getting errors in the Google Cloud logs when a document is created. The error is related to new CloudTasksClient(). If I remove that and just log a simple string then I am seeing the record and log when a document is created an no errors. @google-cloud/tasks is updated. even if I just try to log logger.log('CloudTasksClient', CloudTasksClient); without instantiating it, I get these errors as well which seems to point to an import issue but I cannot for the life of me figure out what it is. Any ideas?

import { initializeApp } from 'firebase-admin/app';
import * as logger from 'firebase-functions/logger';
import { onDocumentCreated } from 'firebase-functions/v2/firestore';
import { CloudTasksClient } from '@google-cloud/tasks';

initializeApp();

export const onStartSession = onDocumentCreated(
    'userSessionInfo/{userId}/history/{sessionId}',
    async () => {
        const project: string = /* removed */;
        const location: string = 'us-central1';
        const queue: string = 'delay';
        const tasksClient = new CloudTasksClient();
        const queuePath = tasksClient.queuePath(project, location, queue);
        logger.log('queuePath', queuePath);
    },
);

These are the errors. It seems like the class is undefined which is throwing the second error and then the first one is from Firebase being unable to create a snapshot when the document is created because of the undefined error?

Answer 1

There is an issue which is actively investigated: https://github.com/googleapis/google-cloud-node/issues/5000

https://github.com/sofisl seems to be looking into it right now.

A quick fix would be a down-grade to @google-cloud/tasks v4.0.1.
