Hi, thank you for reporting this. I confirmed that this is a regression, and we are preparing a patch for release to NPM.

The patch is here: smithy-lang/smithy-typescript#1773. I will post the version containing the fix when it is ready.

The fix was released in https://www.npmjs.com/package/@smithy/core/v/3.18.2.

To upgrade this transitive AWS SDK dependency, run npm up @smithy/core, an equivalent command if using a different package manager, or reinstall without a lockfile.

To check that the version has been installed, run npm ls @smithy/core.
