Type error: This expression is not callable.

I am getting error with my page

./pages/api/[...all].ts:13:10
Type error: This expression is not callable.
  Type 'typeof import("/Users/joeyoung/_WORKING/joegyoung/node_modules/next-http-proxy-middleware/src/index")' has no call signatures.

This is the source

import { NextApiRequest, NextApiResponse } from "next";
import httpProxyMiddleware from "next-http-proxy-middleware";

const isDevelopment = process.env.NODE_ENV === "development";
const isProduction = process.env.NODE_ENV === "production";

export default (req: NextApiRequest, res: NextApiResponse) => {
	if (isDevelopment) {
		const {
			query: { all },
		} = req;

		return httpProxyMiddleware(req, res, {
			// You can use the `http-proxy` option
			target: `http://localhost:9000/.netlify/functions/${all}`,
			pathRewrite: {
				"^/api+": "",
			},
		});
	} else {
		res.status(404).send(null);
	}
};

What am I needing to do?

I have fixed my issue by using "iwatakeshi/next-http-proxy-middleware"
