Express proxy + axios + cors: still cors issue - node.js

Question

I've created the following proxy with express:
import express from "express";
import cors from "cors";
import proxy from "express-http-proxy";
const app = express();
app.use(
cors({
origin: "http://localhost:8081",
credentials: true,
})
);
app.use("/", proxy("http://my-website:8810"));
app.listen(3000, () => {
console.log("server listening on port 3000");
});
From the frontend I'm using axios:
axios.defaults.withCredentials = true;
const res = await axios.get("http://localhost:3000", {
auth: {
username: "xxxxx",
password: "xxxxx",
},
headers: {
"Content-Type": "application/json",
},
});
But I still have the following cors issue:
Access to XMLHttpRequest at 'http://my-website:8810' (redirected from
'http://localhost:3000/') from origin 'http://localhost:8081' has been
blocked by CORS policy: Response to preflight request doesn't pass
access control check: No 'Access-Control-Allow-Origin' header is
present on the requested resource.
And after many hours facing this issue... here I am.
Could anyone explain to me what I'm doing wrong here?

Finally it works by using "request", something like:
app.use(
cors({
origin: "http://localhost:8081",
credentials: true,
})
);
router.get("/", (req, res) => {
request(
"http://my-website:8810",
{
auth: {
username: "node_proxy",
password: "password",
},
headers: { Accept: "application/json" },
},
(error, response, body) => {
res.send(body);
}
);
});
