Thanks again for reporting this issue!

It seems like this 403 Forbidden response is due to an invalid CORS request. If you try to open index.html locally, you will likely send an Origin: null header to our back end which is rejected due to security concerns. If you try to load index.html from the web instead, you should be able to execute the uploading-files-basic example without this error.
