I am currently trying to create a middleware that will user's data by fetching an external endpoint with Axios. Axios too, does not work with the middleware. Here is my error when using node-fetch:
Module build failed: UnhandledSchemeError: Reading from "node:buffer" is not handled by plugins (Unhandled scheme).
Webpack supports "data:" and "file:" URIs by default.
You may need an additional plugin to handle "node:" URIs.
Any idea why this happens?
Here is my code:
import fetch from "node-fetch"
import { getSession } from "next-auth/react";
import { NextMiddleware, NextResponse } from "next/server";
export const middleware: NextMiddleware = async (req, ev) => {
const session = await getSession() as any;
const user = await fetch("some-url", {
headers: {
Authorization: `Bearer ${session?.user?.someproperty}`,
},
});
if (user.statusCode !== 200) return NextResponse.redirect(req.url);
else return NextResponse.next();
};
In my case I was using axios inside middleware, and got the following error
error - node_modules\axios\lib\core\dispatchRequest.js (53:0) @ dispatchRequest
TypeError: adapter is not a function
I had to install axios-fetch-adapter according to this question
My code would like
import type { NextFetchEvent, NextRequest } from 'next/server'
import fetchAdapter from '@vespaiach/axios-fetch-adapter'
import axios from 'axios'
export async function middleware(req: NextRequest, ev: NextFetchEvent) {
const axiosInstance = axios.create({
adapter: fetchAdapter
})
const data = await axiosInstance.get('/whatever-url')
// the rest of the code
}
Or if you already had a preconfigured instance with custom options
import type { NextFetchEvent, NextRequest } from 'next/server'
import fetchAdapter from '@vespaiach/axios-fetch-adapter'
import axiosInstance from './the-path-of-your-instance'
export async function middleware(req: NextRequest, ev: NextFetchEvent) {
axiosInstance.defaults.adapter = fetchAdapter
const data = await axiosInstance.get('/whatever-url')
// the rest of the code
}
