Why do I still get error code 400 from this API request to Coinbase Pro?

问题

I've followed the instructions on the Coinbase Pro developers page for authentication with API Key and no matter what I try I always get error code 400 using CryptoJS and React / React Native.

https://docs.pro.coinbase.com/#api-key-permissions

import CryptoJS from 'crypto-js';
import axios from 'axios';
import { Buffer } from 'buffer';

const key = '<removed';
const secret = '<removed>';
const passphrase = '<removed>';
const method = 'GET';
const uri = 'https://api.pro.coinbase.com/accounts';
const requestPath = '/accounts';
const timestamp = Math.floor(Date.now() / 1000);
const message = `${timestamp}${method}${requestPath}`;
const secret64 = Buffer.from(secret, 'base64').toString('ascii');
const hmac = CryptoJS.HmacSHA512(message, secret64);
const signed = CryptoJS.enc.Base64.stringify(hmac).toString();

const headers = {
  'User-Agent': 'reactnative',
  'Content-Type': 'application/json',
  'CB-ACCESS-KEY': key,
  'CB-ACCESS-SIGN': signed,
  'CB-ACCESS-TIMESTAMP': timestamp,
  'CB-ACCESS-PASSPHRASE': passphrase,
  'CB-VERSION': '2019-05-22'
};

axios
  .get(uri, {
    method,
    headers
  })
  .then((response) => {
    console.log(response);
  })
  .catch((error) => {
    console.log(error);
  });



Other variations I have tried:

// const secret64 = Buffer.from(secret, 'base64').toString('ascii');
// const secret64 = Buffer.from(secret, 'base64').toString();
// const secret64 = Buffer.from(secret, 'base64');
// const signed = CryptoJS.HmacSHA512(message, secret64).toString();
// const signed64 = Buffer.from(signed).toString('base64');

// const hmac = CryptoJS.HmacSHA512(message, secret64).toString(CryptoJS.enc.Hex);
// const hmac = CryptoJS.HmacSHA512(message, secret64).toString(CryptoJS.enc.Hex);
// const signed = CryptoJS.enc.Base64.stringify(hmac);
// const signed = Buffer.from(hmac.toString()).toString('base64');
// const utf = CryptoJS.enc.Utf8.parse(hmac);
// const signed = CryptoJS.enc.Base64.stringify(utf).toString();
// const hash = CryptoJS.HmacSHA512(message, secret);
// const signed = CryptoJS.enc.Base64.stringify(hmac);

Error: Request failed with status code 400

What am I doing wrong?
