upload_fileobj function is not working after boto3 version 1.35.0 , fails with "error occurred (SignatureDoesNotMatch) when calling the PutObject operation"

[gitmgh]

WIth the version of boto3==1.37.25 the function upload_fileobj fails with error "error occurred (SignatureDoesNotMatch) when calling the PutObject operation". without changing the code I was trying for earlier version and it passed at boto3==1.35.0. I would like to know if the function will be supported in any future release or do we have any alternate function?
