UnhandledPromiseRejectionWarning: TypeError: versionRouter.route is not a function

[arvindgemini]

Getting exception error, added sample code only

import * as versionRouter from 'express-version-route';
import { Router, Handler, Request, Response } from 'express';
const routesMap = new Map<string, Handler>();
const route = Router();

export default (app: Router) => {
app.use('/version-customer', route);

routesMap.set('1.0', (req, res, next) => {
return res.status(200).json({ message: 'hello to you version 1.0' });
});

routesMap.set('default', (req, res, next) => {
return res.status(200).json({ message: 'hello to you, this is the default route' });
});

route.get('/test', versionRouter.route(routesMap));
};

I think you're not importing it correctly.
What if you try the following import?

import versionRouter from 'express-version-route';
