downloadRequestHeaders config does not work about react-papaparse

[Bunlong]

@sananguliyev The problem is you haven't allowed origin header on amazon s3. You can follow this guidance to solve this problem. If it works please let me know. Thanks!

I already added the CORS configuration to S3. It's an issue on Chrome level. I disabled out of blink on Chrome and it's gone.

Do you have any idea about Refused to get unsafe header "Content-Range" this error?

@sananguliyev Could you please follow this guidance and try the following CORES configuration:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
  <CORSRule>
    <AllowedOrigin><!-- insert your origin here --></AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedHeader>Range</AllowedHeader>
    <MaxAgeSeconds>3000</MaxAgeSeconds>
    <ExposeHeader>Accept-Ranges</ExposeHeader>
    <ExposeHeader>Content-Range</ExposeHeader>
    <ExposeHeader>Content-Encoding</ExposeHeader>
    <ExposeHeader>Content-Length</ExposeHeader>
    <AllowedHeader>Authorization</AllowedHeader>
  </CORSRule>
</CORSConfiguration>

Thanks. I will try to expose headers, too.

@sananguliyev Yes, you are welcome. Thanks!
