How can I use one script inside another script?

[Ish Modi]

This is my code, but it's not working. How can I fix it?

const axios = require('axios');
const preProcess = require('/app/preProcessingData');

async function beforeRender(req, res) {
    try {
        const payload = req.data;
        // You can now call preProcess here if needed
        preProcess('someTemplateName');
    } catch (error) {
        console.error('Error in beforeRender:', error);
    }
}

function preProcess (templateName) {

    console.log(templateName,'templateName')
}
module.exports = preProcess;
