Can you give the following details?

Are you using typescript or javascript?
Are you importing the module using require or import? Also, send the import or require statement you are using

Hi, the code was following to preserve backward compatibility with node v14:

const ImageKit = require('imagekit');

// imagekit auth
app.get("/imagekit_auth", function(request, response) {
	const imagekit = new ImageKit(require('./config').imagekit);
	try {
		const token = request.query.token || uuid.v4();
		const expiration = request.query.expire || parseInt(Date.now()/1000)+ (60 * 10); // Default expiration in 10 mins
		const signatureObj = imagekit.getAuthenticationParameters(token, expiration);
		response.status(200).send(signatureObj);
	} catch (err) {
		console.error("Error while responding to imagekit_upload request:", JSON.stringify(err, undefined, 2));
		response.status(500).send("Internal Server Error");
	}
});

The code was taken directly from your guide.
