Admin component - getPolyfill is not a function

API Platform version(s) affected: 2.6 "@api-platform/admin": "^2.6.4"

Description
A created my API on Api Platform Symfony backend - everything is working perfect - thanks for your hard work on ApiPlatform!

My next step is to create easy admin panel to manage and moderate some records.

When I am going throught the documentation steps:

yarn create react-app my-admin
yarn add @api-platform/admin
I have also found about: yarn add isomorphic-fetch (as I am working on docker node container)
yarn start my admin app is reporting error:

TypeError: getPolyfill is not a function ./node_modules/array.prototype.foreach/index.js node_modules/array.prototype.foreach/index.js:10 7 | 8 | var implementation = require('./implementation'); 9 | var getPolyfill = require('./polyfill');

10 | var polyfill = getPolyfill(); 11 | var shim = require('./shim'); 12 | 13 | var $slice = callBound('Array.prototype.slice');

I am working with admin app on Docker Container based on node:lts-alpine, but when I was on 12.2 result was the same.

Any ideas/suggestions?

How to reproduce
Just go through the Documentation steps of Admin component: https://api-platform.com/docs/admin/getting-started/

api-platform / admin
