How to access all response headers?

[datta202]

I uploaded one file on aws s3. In response I get Etag and I want to access that header.

I checked inside useBatchFinishListener hook, but cannot get all response headers.

Could you please tell me how can I access all response headers?

I fixed above issue. In aws cors settings, "Access-Contorl-Expose-Headers" header was missing.
Thanks
