[REQUIRED] Version info

node: v18.16.0

firebase-functions: 4.3.1

firebase-tools: 12.4.0

firebase-admin: 11.8.0

[REQUIRED] Test case

I have successfully deployed a cloud function: but it gives PERMISSION_DENIED when triggered.

[REQUIRED] Steps to reproduce

import * as functions from "firebase-functions";
import * as admin from "firebase-admin";

admin.initializeApp();

export const setTimestampsOnCreate = functions.firestore
  .document("listings/{listingId}")
  .onCreate((snapshot) => {
    const currentTime = admin.firestore.FieldValue.serverTimestamp();
    return snapshot.ref.set(
      {
        createdAt: currentTime,
        updatedAt: currentTime,
      },
      {
        merge: true,
      }
    );
  });

Then, firebase deploy.

[REQUIRED] Expected behavior

createdAt and updatedAt appear in the new listing document.

[REQUIRED] Actual behavior

Nothing appears, and this appears in the Logs Explorer of that function:
