Duplicate File awsSdkSigV4AConfigSelector.d.ts breaking deployments

• I've searched for previous similar issues and didn't find any solution.

Describe the bug

Our builds recently started failing when updating from 3.645.0 to 3.649.0, and we were able to trace it to duplicate awsSdkSigV4AConfigSelector.d.ts files. When I try to unzip our build zip file, I get this error. I'm guessing there's a case sensitivity issue.

SDK version number

@aws-sdk/package-name@version, ...

Which JavaScript Runtime is this issue in?

Node.js

Details of the browser/Node.js/ReactNative version

v20.12.1

Reproduction Steps

We're using azure with github actions so it's a little hard to provide repro instructions. Hoping the bug description is enough.

Observed Behavior

Our logs showed

Run From Package Initialization failed. Zip Contains 2 duplicate files with identical name in the same path
It was only when trying to unzip that we could see that the issue came from the aws package.

Expected Behavior

zip-based builds to succeed. No duplicate files.

Possible Solution

No response

We also started seeing this yesterday.

The two files we see:

node_modules/@aws-sdk/core/dist-es/submodules/httpAuthSchemes/aws_sdk/awsSdkSigV4AConfigSelector.js
node_modules/@aws-sdk/core/dist-es/submodules/httpAuthSchemes/aws_sdk/AwsSdkSigV4AConfigSelector.js

Content in the 2 files is exactly the same as well.

I'm able to see duplicate files in @aws-sdk/core@3.649.0 in operating system with case sensitive file system, like Linux.

$ mkdir test-install && cd test-install

$ test-install> npm install @aws-sdk/core@3.649.0 --save-exact

$ test-install> ls -1a node_modules/@aws-sdk/core/dist-es/submodules/httpAuthSchemes/aws_sdk
.
..
awsSdkSigV4AConfigSelector.js
AwsSdkSigV4AConfigSelector.js
AwsSdkSigV4ASigner.js
AwsSdkSigV4Signer.js
index.js
resolveAwsSdkSigV4AConfig.js
resolveAwsSdkSigV4Config.js

Also verified in npmjs file browser https://www.npmjs.com/package/@aws-sdk/core?activeTab=code

This happened as TurboRepo cached artifact from an intermediate state of the @aws-sdk/core from a developer workspace, and it reused that cache from release since the source artifacts hadn't changed.

One long-term fix would be clean like rimraf dist-es && build:es to all our package.json build scripts.

Thank you very much.
