Node js cors proxy results in forbidden

I'm trying to communicate with an api with react. I was getting a cors error so i created a proxy api. I'm still getting a 403 error but this time it's different. I get a captcha error. I get data when i open the url in browser and also when i make a request in postman, but not through node js

const express = require('express');
const cors = require("cors");
const axios = require('axios');
const app = express();
const port = process.env.PORT || 8000;

app.use(cors({
  origin: '*'
}));

app.get("/", (req, res) => {
  const url = `URL_TO_EXTERNAL_API`;
  axios.get(url)
  .catch(error => console.log(error))
  .then(resp => {
    console.log(resp);
  });
});

app.listen(port, () => console.log(`http://localhost:${port}`));

here's a portion of the error i get

Here's the react request ->

fetch(local, { 
  method: 'get', 
  headers: new Headers({
    'Content-Type': 'application/json'
  })
}).then(response => {
  return response.json();;
}).then(data => {
  this.setState({ announcements: data })
});

where local is "http://localhost:8000?params..."

Do you know why the current solution is not working ?
