Here is my code:

const functions = require("firebase-functions");
const admin = require("firebase-admin");
const {Client} = require("@elastic/elasticsearch");

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

const env = functions.config();

const auth = {
  username: env.elasticsearch.username,
  password: env.elasticsearch.password,
};

const client = new Client({
  node: env.elasticsearch.url,
  auth: auth,
});

exports.createTest = functions.firestore
    .document("tests/{testId}")
    .onCreate( async (snap, context) => {
        await client.index({
            index: "temp",
            type: "_doc",
            id: snap.id,
            body: snap.data(),
        })
    });

but I am getting the following error.

createTest
