Fixed in smithy-lang/smithy-typescript#1408

Actually I’ll leave this issue open until smithy is bumped.

Workaround until the minimum version is bumped is to update your lockfile or make a fresh install.

The minimum node-http-handler dependency version in the current version of the SDK is high enough to guarantee including the fix, so I'm closing this now.
