Firebase cloud functions: TypeScrip How to split a function into multiple files?

I want to use admin and searchClient in different files.

export = {admin, searchClient}; Adding this code throws an error.

Error: Failed to load function definition from source: Failed to generate manifest from function source: RangeError: Maximum call stack size exceeded

Index.ts

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

admin.initializeApp(functions.config().firebase);

const searchClient = algoliasearch(env.algolia.appid, env.algolia.apikey);

....

exports.query = require('./query');
exports.products = require('./products');

query.ts

import * as functions from 'firebase-functions';
import {searchClient} from "./index";

const requestIndex = searchClient.initIndex("allRequests");

products.ts

import * as functions from 'firebase-functions';
import {admin} from "./index";

const firestoreDb = admin.firestore();

The problem was fixed by splitting the initial setup routine into a new file.
