I'm trying to implement some security checks to my cloud function triggers, but as I discovered my current set up results in an infinite loop from the onCreate and onDelete triggers when doc is not valid. How would I go about using onCreate and onDelete triggers for security without resulting in an infinite loop or is there another way that can achieve this without using firestore security rules?

  export const createEventTrigger = functions.firestore.document("events/{id}").onCreate(async (snapshot, context) => {

    const event = snapshot.data() as Event;

    const isValid = await isEventDocumentCreateValid(context, event);

    if (!isValid) {
      // Delete the document if it’s invalid
      console.log(
        `Deleting invalid document for user ${getInvokerUid(context)}`
      );
      await snapshot.ref.delete();
    }
  });

  export const deleteEventTrigger = functions.firestore.document("events/{id}").onDelete(async (snapshot, context) => {
    // Contents of the document as a JavaScript object
    const event = snapshot.data() as Event;

    const isValid = await isEventDocumentDeleteValid(context, event);

    if (!isValid) {
      // Add back the document if it’s invalid
      console.log(
        `Adding back doc after invalid document delete for user ${getInvokerUid(
          context
        )}`
      );
      await snapshot.ref.set(event);
    }
  });
