@Fedema92 Do you use webpack >= 5? I guess this is due to https://webpack.js.org/blog/2020-10-10-webpack-5-release/#automatic-nodejs-polyfills-removed. If so try to add the Node.Js Buffer Polyfill: webpack/changelog-v5#10 (comment)

Besides that I could not reproduce the issue. Sandboxes used: swagger-ui-react, swagger-ui-react-webpack

Yes, I had just updated webpack to v6. I had added the ProvidePlugin to webpack configuration and it works like a charm.
Thanks @mathis-m

I replaced "module": "CommonJS" with "module": "ES6" in typescript.config and it worked. I didn't use any polyfiles and used a minimal webpack build.
