I am getting this TLS & Socket hang up error each time my firebase function tries to access a collection group in my firestore database, any ideas what could be causing this error?

Exception from a finished function: FetchError: request to ... failed, reason: socket hang up

Firestore query error: FetchError: request to ... failed, reason: Client network socket disconnected before secure TLS connection was established"
const {onSchedule} = require("firebase-functions/v2/scheduler");
const {initializeApp} = require("firebase-admin/app");
const {getFirestore} = require("firebase-admin/firestore");
initializeApp();
const db = getFirestore();
exports.checkOrders = onSchedule(
    {
      timeoutSeconds: 300,
      region: "europe-central2",
      schedule: "05 03 * * *",
    }, async (event) => {
      const now = new Date();
      const today = now.setHours(3, 0, 0, 0);
      const yearToday = now.getFullYear();
      const monthToday = now.getMonth() + 1;
      const dayToday = now.getDate();
      const formattedToday = `${yearToday}, ${monthToday < 10 ? "0" + monthToday : monthToday}, ${dayToday < 10 ? "0" + dayToday : dayToday}`;

      console.log(today);
      console.log(formattedToday);

      const mainSnapshot = await db.collection("xxx")
          .where("activity_status", "in", ["Active", "ActiveLast", "Pending", "Inactive", "", "Error"])
          .get();

      mainSnapshot.forEach((doc) => {
        const Data = doc.data();
        indexFunctions(Data, today, formattedToday);
      });

      async function indexFunctions(Data, today, formattedToday) {
        let retryCount = 0;
        const maxRetries = 3;

        const updateObject = {};
        let iterationCount = 1;
        const parentID = String(Data.id);
        const updateBatch = db.batch();
        while (retryCount < maxRetries) {
          try {
            const querySnapshot = await db.collectionGroup("qqq")
                .where("parent_id", "==", parentID).get();

// This is where the code starts throewing those errors, so i dont need to show the rest of the code.

My functions have the right permissions & the problem doesn’t seem to be coming from my code, at least i don’t think, because i tried stripping it down to the bone but still got these errors. I have tried checking for proxies, updating all dependancies and everything i could think of. Any help would be appreciated.
