Yeah, and AWS SDK maintainers are only giving us the cold shoulder on this

github.com/aws/aws-sdk-js-v3

s3.deleteObjects sends CRC32 checksum even if `requestChecksumCalculation` is set to `WHEN_REQUIRED`

### Checkboxes for prior research - [x] I've gone through [Developer Guide](htt…ps://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide) and [API reference](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest) - [x] I've checked [AWS Forums](https://forums.aws.amazon.com) and [StackOverflow](https://stackoverflow.com/questions/tagged/aws-sdk-js). - [x] I've searched for [previous similar issues](https://github.com/aws/aws-sdk-js-v3/issues) and didn't find any solution. ### Describe the bug s3.deleteObjects sends CRC32 checksum even if `requestChecksumCalculation` is set to `WHEN_REQUIRED` ### Regression Issue - [x] Select this option if this issue appears to be a regression. ### SDK version number @aws-sdk/client-s3@2.729.0 ### Which JavaScript Runtime is this issue in? Node.js ### Details of the browser/Node.js/ReactNative version All ### Reproduction Steps ```js import { S3 } from "@aws-sdk/client-s3"; import { NodeHttpHandler } from "@smithy/node-http-handler"; class CustomHandler extends NodeHttpHandler { constructor() { super(); } printChecksumHeaders(prefix, headers) { for (const [header, value] of Object.entries(headers)) { if ( header === "content-md5" || header.startsWith("x-amz-checksum-") || header.startsWith("x-amz-sdk-checksum-") ) { console.log(`${prefix}['${header}']: '${value}'`); } } } async handle(request, options) { this.printChecksumHeaders("request", request.headers); const response = await super.handle(request, options); this.printChecksumHeaders("response", response.response.headers); return response; } } const client = new S3({ requestHandler: new CustomHandler(), requestChecksumCalculation: "WHEN_REQUIRED", }); const Bucket = "test-flexible-checksums-v2"; // Update to your test bucket name. const prepareClient = new S3(); // Populate an object in the bucket, as deleteObjects requires at least one. await prepareClient.putObject({ Bucket, Key: "helloworld.txt", Body: "helloworld" }); // Get list of objects to delete. const response = await prepareClient.listObjectsV2({ Bucket }); const Objects = response.Contents.map(({ Key }) => ({ Key })); await client.deleteObjects({ Bucket, Delete: { Objects } }); ``` ### Observed Behavior The CRC32 checksum is sent even if `requestChecksumCalculation` is set to `WHEN_REQUIRED` ```console $ node test.mjs request['x-amz-sdk-checksum-algorithm']: 'CRC32' request['x-amz-checksum-crc32']: 'uDrkBQ==' ``` ### Expected Behavior When `requestChecksumCalculation` is set to `WHEN_REQUIRED`, should it send `md5` like it was done in `<=v3.729.0`? Example output in `v3.726.0` ```console $ node test.mjs request['content-md5']: 'rl/UEqX25ygZIHP8TWK6/g==' ``` ### Possible Solution _No response_ ### Additional Information/Context _No response_
