Error: The 'cache' field on 'RequestInitializerDict' is not implemented.

Started seeing this error when using AWS S3 SDK to GetObject in a Cloudflare Pages App, which runs on workerd:

✘ [ERROR] Error: The 'cache' field on 'RequestInitializerDict' is not implemented.

 at FetchHttpHandler.handle
  (file:///.../node_modules/@smithy/fetch-http-handler/dist-es/fetch-http-handler.js:77:30)
      at null.<anonymous> (async

I will attempt a downgrade. I may try a standalone app to share.

Update pinning to 3.2.5 resolves the error.

Also running into this... cache setting is not implemented in Cloudflare workers.

Same, cloudflare workerd runtime.

Had to downgrade to 3.645.0

"@aws-sdk/client-s3": "3.645.0",
"@aws-sdk/s3-request-presigner": "3.645.0",

I believe the error is here: https://github.com/smithy-lang/smithy-typescript/blob/main/packages/fetch-http-handler/src/fetch-http-handler.ts#L115

This is the breaking commit: cf9257e

We will accept the patch once approved, but until then there is a workaround posted in the linked issue

const client = new SDKClient({
  requestHandler: {
    // Cloudflare doesn't support the cache option, so we remove it.
    requestInit: () => ({
      cache: undefined,
    }),
  },
});

released in https://www.npmjs.com/package/@smithy/fetch-http-handler/v/3.2.8

confirmed fixed for me with latest aws client s3 + v3.2.8 of fetch-http-handler
