TypeError: Cannot assign to read only property '__esModule' of object '#<Object>'

Intended outcome:
Send a mutation to a graphql endpoint with the following code:

const fetch = require('node-fetch');
const { ApolloClient, HttpLink, InMemoryCache } = require('apollo-boost');
const gql = require('graphql-tag');

const replaceItemsMutation = gqlmutation ReplacePlaylistItems($playlistItems: [PlaylistItemInput!]!) { replacePlaylistItems(playlistItems: $playlistItems) { id } }
async function createClient() {
const headers = await getAuthHeaders();

return new ApolloClient({
link: new HttpLink({
uri,
headers,
fetch
}),
cache: new InMemoryCache()
});
}

async function replacePlaylistItems(playlistItems) {
if (!client) {
client = await createClient();
}
await client.mutate({
mutation: replacePlaylistItemsMutation,
variables: { playlistItems }
})
}

module.exports = {
replacePlaylistItems
}

Actual outcome:
Executing the script in the command line with "node script.js" produces the following error:
Object.keys(ApolloClient__default).forEach(function (key) { exports[key] = ApolloClient__default[key]; });

I am able to still get this script to work if I enclude:
const defineProperty = Object.defineProperty;
Object.defineProperty = function (exports, name) {
if (name === '__esModule') {
exports[name] = true;
return;
}
return defineProperty.apply(this, arguments)
}
at the top of the file that imports and uses the above code.

Other notes:
changing 'use strict' to 'use loose' in bundle.cjs.js allowed the script to work without errors.
I noticed that both \apollo-boost\lib\bundle.cjs.js and \apollo-boost\lib\index.js both have the following: Object.defineProperty(exports, '__esModule', { value: true }); (lines 3 and 2)
commenting out Object.defineProperty(exports, '__esModule', { value: true }); in bundel.cjs.js also allowed the script to work without errors.

This sounds a lot like #4843. Try upgrading apollo-boost to 0.4.1 and see if that fixes it

Closing because I strongly suspect @dylanwulf is correct. Please reopen this issue if updating apollo-boost to the latest version does not fix the problem!
