Axios.Post not adding to cart

[wchorski]

linking my followed along project here
my github repo/ utils/cart.js

spots that need help are labeled with // TODO HELP -- *

when running the Woocommerce endpoints in POST MAN, I get desired result of adding to cart, and getting updated cart when running those enpoints in axios in the app I still get null return . I'll link the code snippet below

I've tried

• trying browser in incognito
• using a different browser

import { getSession, storeSession } from './cart-session';
import { getApiCartConfig } from './cart-api';
import axios from 'axios';
import { WC_CART } from 'utils/endpoints';
import { isEmpty, isArray } from 'lodash';

export const addToCart = ( productId, qty = 1, setCart, setIsAddedToCart, setLoading ) => {
	const storedSession = getSession();

  // TODO HELP -- using enpoints in POST MAN works as it should, but not here
	axios.post( WC_CART, {
			product_id: productId,

		addOrViewCartConfig,
	)
		.then( ( res ) => {

      console.log('data post: ', res?.data);
      
      if ( isEmpty( storedSession ) ) { storeSession( res?.headers?.[ 'x-wc-session' ] ) }

			setIsAddedToCart(true)
