.clone() returns a new instance but can not produce .handler()

[BounSweFerhatSal]

when creating a router as below in a separate file , to use as a base as below :

import { createRouter } from "next-connect";

const pipeLineRouter = createRouter();
export default pipeLineRouter
  .use(jwtTokenValidator_middleware)
  .use(dbConnection_middleware);

then importing in another API file by cloning the router as below (as suggested) :

import apiPipeline from "/lib/apiPipeline";

const router = apiPipeline.clone();
router.get(async (req, res) => {
    //......
});

export default router.handler(errorCather);

router.handler() fails with error :

TypeError: router.handler is not a function

However, console.log(router) gives exact same router object properties which has been cloned.
