Advanced Trade REST API Authentication failure, nodejs

I don’t get my nodejs code working for the REST API when a JWT is needed. The web socket (different code) using the same keys is working fine, a REST call to “time” (public service) is also working fine. Why is the JWT failing?

AxiosError: Request failed with status code 401

This is my code:

const { sign } = require('jsonwebtoken');
const crypto = require('crypto');
const axios = require('axios');

// Configuration for JWT
const key_name = 'organizations/...';
const key_secret = '-----BEGIN EC PRIVATE KEY-----\n...-----END EC PRIVATE KEY-----\n';

// What and Where:
const url = 'https://api.coinbase.com';
const service_name = "retail_rest_api_proxy"

const request_method = 'GET';
const request_path = '/api/v3/brokerage/accounts'; // time works fine, accounts does not

const algorithm = 'ES256';
const uri = request_method + ' ' + url + request_path;

const token = sign(
    {
        aud: [service_name],
        iss: 'coinbase-cloud',
        nbf: Math.floor(Date.now() / 1000),
        exp: Math.floor(Date.now() / 1000) + 120,
        sub: key_name,
        uri,
    },
    key_secret,
    {
        algorithm,
        header: {
            kid: key_name,
            nonce: crypto.randomBytes(16).toString('hex'),
        },
    }
);

// Configuring the API request
let config = {
    method: request_method,
    url: url + request_path,
    headers: {
        'Content-Type': 'application/json',
        Authorization: `Bearer ${token}` // Adding the Authorization header
    }
};

// Executing the API call with axios
axios(config)
    .then((response) => {
        console.log(JSON.stringify(response.data));
    })
    .catch((error) => {
         console.log(error);
    });

Thanks!

Remove https:// from host/url when generating token.
