[rcoh]

looks like a bug, thanks for reporting we'll get a fix out

@jaketreacher This issue is caused by the fact that S3 isn't returning XML in the form specified by their model and the Rust SDK validates response XML. Most other SDKs ignore name mismatch issues with the response XML's root element. We can address this issue by suppressing that validation for S3 specifically. I'm going to look into what that would entail.

Thanks for surfacing this issue!

I have a fix for this https://github.com/awslabs/smithy-rs/pull/1665 If it gets merged by tomorrow, I'll run a release.

The fix for this went out with the 2022-08-31 release. Thanks again for reporting this!
