I’m trying to schedule a job when the user set the account to delete. Here’s the appraoch:

const accountDeletionTrigger = functions.firestore
    .document('users/{userId}')
    .onUpdate(async (change, context) => {
        try {
            const userId = context.params.userId;
            const newValue = change.after.data();
            const previousValue = change.before.data();

            if (newValue.deleted && !previousValue.deleted) {
                const deletionTime = new Date(Date.now() + 15 * 1000);

                const task = await admin.scheduler.createJob({
                    name: `projects/${projectId}/locations/${location}/jobs/${jobId}`,
                    schedule: deletionTime.toISOString(),
                    timeZone: 'utc',
                    httpTarget: {
                        uri: `${baseUrl}/v1/deleteAccount`,
                        httpMethod: 'POST',
                        body: JSON.stringify({ userId }),
                    }
                });

                await admin.firestore().doc(`users/${userId}`).update({
                    deletionTaskId: task.name,
                    accountSetToDeleteAt: deletionTime,
                });
            }
        } catch (error) {
            console.error('Account deletion scheduling failed:', error);
        }
    });

But unfortunately, the logs on the cloud function says something like this:

{
  "textPayload": "Account deletion scheduling failed: TypeError: Cannot read properties of undefined (reading 'createJob')",
  "insertId": "676bc1560007e84741c1405d",

      "region": "us-central1"
    }
  },

    "execution_id": "j5w1h0iarwjy",
    "runtime_version": "nodejs18_20241215_18_20_5_RC00"
  },
  "logName": "projects/devxi-dev/logs/cloudfunctions.googleapis.com%2Fcloud-functions",
  "trace": "projects/devxi-dev/traces/4dc6f1ed7b9b0ca1e67d16f0dfe0c9b1",
  "receiveTimestamp": "2024-12-25T08:24:54.852172639Z"
}

Is there something I’m missing on? createJob doesn’t exists for Firebase admin, then what’s the new way/alternative for this?

I’ve tried exploring the docs but couldn’t find something. I do come to know about pub/sub triggers, but those are for calling a function in recursive way, I don’t want that.

Any kind of help would be appreciated. Thanks
