firebase document update trigger function error - node.js

Question

I am trying to stream insert the data into the Bigquery table and have the below issues with function. Not sure where is an error in the code. I have followed this to achieve with realtime data.
https://github.com/googleapis/nodejs-bigquery/blob/main/samples/insertRowsAsStream.js
Function returned undefined, expected Promise or value
const functions = require("firebase-functions");
const {BigQuery} = require("#google-cloud/bigquery");
exports.onWriteTrigger = functions
.firestore
.document("leaseCompany/{documentId}")
.onWrite((change, context) => {
/*
onCreate: google.firestore.document.create
onUpdate: google.firestore.document.update
onDelete: google.firestore.document.delete
*/
const row = {
// insertId: document.data.id,
// json: {
timestamp: context.timestamp,
name: change.after.data().name,
// documentName: context.resource.name,
documentId: change.after.id,
eventId: context.eventId,
data: change.after.data().country,
};
// console.log(insertRows);
async function insertBigQuery(rows) {
try {
console.log(row);
const datasetName = "firestore_export";
const tableName = "leaseCompany";
const bigqueryClient = new BigQuery();
const ds = bigqueryClient.dataset(datasetName);
const tbl = ds.table(tableName);
await tbl.insert(rows)
.then((data) => {
return true;
})
.catch((err) => {
// An API error or partial failure occurred.
if (err.name === "PartialFailureError") {
console.log("Error Sending Notifications", err);
return false;
}
});
} catch (err) {
console.error(`table.insert: ${JSON.stringify(err)}`);
return err;
}
}
// console.log(row);
insertBigQuery(row);
});

you need to return promise or value from you function
async function insertBigQuery(rows) {
try {
console.log(row);
const datasetName = "firestore_export";
const tableName = "leaseCompany";
const bigqueryClient = new BigQuery();
const ds = bigqueryClient.dataset(datasetName);
const tbl = ds.table(tableName);
return tbl.insert(rows)
.then((data) => {
return true;
})
.catch((err) => {
// An API error or partial failure occurred.
if (err.name === "PartialFailureError") {
console.log("Error Sending Notifications", err);
return false;
}
});
} catch (err) {
console.error(`table.insert: ${JSON.stringify(err)}`);
return err;
}
}
return insertBigQuery(row);
