[REQUIRED] Steps to reproduce

V1

/* eslint-disable max-len */
import * as admin from "firebase-admin";
import * as functions from "firebase-functions/v1";

admin.initializeApp();
const db = admin.firestore(
  functions.config().firebase
);
const logCollection = "logs";

export const updateLogs = functions.pubsub.schedule(
  "every 24 hours",
).onRun(async () => {
  try {
    const totalCollections = await db.listCollections();
    console.log(`Checking for expired logs in ${totalCollections.length} collections...`);
    const logsCollection = db.collection("logs");
    const logsSnapshot = await logsCollection.get();
    console.log(`Checking for expired logs... in ${logCollection} against ${logsSnapshot.size} documents`);
    if (logsSnapshot.empty) {
      console.log("Not found in logs collection....");
      return; // Return nothing instead of null
    }

    const currentDate = new Date();
    const batch = db.batch();

    logsSnapshot.forEach((doc) => {
      const logData = doc.data();
      const expiryDateString = logData.expiryDate;

      // Ensure expiryDate is correctly parsed
      const expiryDate = expiryDateString ? new Date(expiryDateString) : null;

      // Convert both dates to UTC to ensure correct comparison
      const isExpired = expiryDate ? expiryDate.getTime() <= currentDate.getTime() : false;
      console.log(`Doc ID: ${doc.id}, Expiry Date: ${expiryDate}, Current Date: ${currentDate}, Is Expired: ${isExpired}`);
      batch.update(doc.ref, { isExpired });
    });

    await batch.commit();
    console.log("Expiry check and update completed.");
    return;
  } catch (error) {
    console.error("Error checking expiry:", error);
  }
}
);

V2

/* eslint-disable max-len */
import * as admin from "firebase-admin";
import * as functions from "firebase-functions";

admin.initializeApp();
const db = admin.firestore(
  functions.config().firebase
);
const logCollection = "logs";

export const updateLogs = functions.scheduler.onSchedule(
  {
    schedule: "0 0 * * *", // Runs at midnight UTC every day
    timeZone: "Etc/UTC",
    retryCount: 3,
    memory: "256MiB", // Optional: Customize memory allocation
    timeoutSeconds: 60, // Optional: Set timeout for the function
  },

  async (event) => {
    try {
      const logsCollection = db.collection("logs");
      const logsSnapshot = await logsCollection.get();
      console.log(`Checking for expired logs... in ${logCollection} against ${logsSnapshot.size} documents`);
      if (logsSnapshot.empty) {
        console.log("Not found in logs collection....");
        return; // Return nothing instead of null
      }

      const currentDate = new Date();
      const batch = db.batch();

      logsSnapshot.forEach((doc) => {
        const logData = doc.data();
        const expiryDateString = logData.expiryDate;

        // Ensure expiryDate is correctly parsed
        const expiryDate = expiryDateString ? new Date(expiryDateString) : null;

        // Convert both dates to UTC to ensure correct comparison
        const isExpired = expiryDate ? expiryDate.getTime() <= currentDate.getTime() : false;
        console.log(`Doc ID: ${doc.id}, Expiry Date: ${expiryDate}, Current Date: ${currentDate}, Is Expired: ${isExpired}`);
        batch.update(doc.ref, { isExpired });
      });

      await batch.commit();
      console.log("Expiry check and update completed.");
      return;
    } catch (error) {
      console.error("Error checking expiry:", error);
    }
  }
);

[REQUIRED] Expected behavior

Documents can be fetched from cloud functions without any additional authentication

[REQUIRED] Actual behavior

No collections/documents found

Were you able to successfully deploy your functions?

Hi @maheshj01,

Before I look into this issue, did you ever figure out the problem or find a workaround?

[maheshj01]

@CorieW I haven't been able to figure out the problem

I managed to get this working with the following code:

/* eslint-disable max-len */
import * as admin from "firebase-admin";
import * as functions from "firebase-functions";

const app = admin.initializeApp({
  credential: admin.credential.applicationDefault(),
});
const db = app.firestore();

const logCollection = "logs";

export const updateLogs = functions.scheduler.onSchedule(
  {
    schedule: "0 0 * * *", // Runs at midnight UTC every day
    timeZone: "Etc/UTC",
    retryCount: 3,
    memory: "256MiB", // Optional: Customize memory allocation
    timeoutSeconds: 60, // Optional: Set timeout for the function
  },

  async (event) => {
    try {
      const logsCollection = db.collection("logs");
      const logsSnapshot = await logsCollection.get();
      console.log(`Checking for expired logs... in ${logCollection} against ${logsSnapshot.size} documents`);
      if (logsSnapshot.empty) {
        console.log("Not found in logs collection....");
        return; // Return nothing instead of null
      }

      const currentDate = new Date();
      const batch = db.batch();

      logsSnapshot.forEach((doc) => {
        const logData = doc.data();
        const expiryDateString = logData.expiryDate;

        // Ensure expiryDate is correctly parsed
        const expiryDate = expiryDateString ? new Date(expiryDateString) : null;

        // Convert both dates to UTC to ensure correct comparison
        const isExpired = expiryDate ? expiryDate.getTime() <= currentDate.getTime() : false;
        console.log(`Doc ID: ${doc.id}, Expiry Date: ${expiryDate}, Current Date: ${currentDate}, Is Expired: ${isExpired}`);
        batch.update(doc.ref, { isExpired });
      });

      await batch.commit();
      console.log("Expiry check and update completed.");
      return;
    } catch (error) {
      console.error("Error checking expiry:", error);
    }
  }
);

Could you give it a try or let me know if there's any further issues?
