Function calling insert operation using pg-promise executes without any success or error message

Question

I have a function bulkInsert() which performs an insert operation using pg-promise and when I call it using the await keyword, it executes without any result (success/error). I am not sure if I am missing anything. Any help is appreciated.

const pgp = require('pg-promise');
const db = pgp({
    host: 'localhost',
    port: 5443,
    database: 'data_base',
    user: 'user_name',
    password: 'pass_word',
});
.......
.......
.......
const bulkInsert = async (data) => { //function when called, executes without any result(success/failure)

    const cs = new pgp.helpers.ColumnSet(['col_A', 'col_B','col_C'], { table: 'table_name' });

    db.tx('massive-insert', t => {
        const processData = data => {
            if (data) {
                const insert = pgp.helpers.insert(data, cs);
                return t.none(insert);
            }
        };
        return t.sequence(index => getNextData(t, index, data).then(processData));
    })
        .then(() => {
            console.log('Success');
        })
        .catch(error => {
            console.log(error);
        });

    function getNextData(t, pageIndex, data) {
        return new Promise((resolve, reject) => {
            const batchSize = 1000;
            const nextDataBatch = [];
            try{
                for (let i = pageIndex; i < data.length; i += batchSize) {
                    const batch = data.slice(i, i + batchSize);
                    nextDataBatch.push(batch);
                }

                if (nextDataBatch.length === 0) {
                    resolve(null);
                } else {
                    resolve(nextDataBatch);
                }
            }
            catch(err){
                reject(err);
            }
        });
    }

};

PS: I am using pg-promise v11.5.4 and in node v18.17.1
