Expected behavior
S3.headBucket should throw error when bucket doesn't exist

[alexforsyth]

Okay so interesting findings. I think this may no longer be a GA blocker, but is still an issue pending investigation.

Region is defaulted to us-west-2

import { S3 } from "@aws-sdk/client-s3";
(async () => {
    let s3Client = new S3({});
    let headBucketParams: HeadBucketRequest = {
        Bucket: "bucket-does-not-exist"
    }
    try {
        let result = await s3Client.headBucket(headBucketParams);    
        console.log("result", result);
    } catch (err){
        console.log(err);
    }
})();

I received a 200 response back

{ '$metadata':
   { httpStatusCode: 200,
     httpHeaders:
      { 'x-amz-id-2':
         '55As9QVGgwofkJ9MCu+yu5jlBU9jpfXX5Te+scb2RxHVttAnJj4adhWNjfwillzOVcFNogRx3hQ=',
        'x-amz-request-id': '14218166C3A99A07',
        date: 'Thu, 29 Oct 2020 16:34:45 GMT',
        'x-amz-bucket-region': 'us-west-2',
        'content-type': 'application/xml',
        'transfer-encoding': 'chunked',
        server: 'AmazonS3' },
     requestId: undefined,
     attempts: 1,

Then I set the region to us-east-1 (global for s3) and I got a 404 back.

 name: 'NotFound',
  '$fault': 'client',
  '$metadata':
   { httpStatusCode: 404,
     httpHeaders:
      { 'x-amz-request-id': '374BA5B6DF577714',
        'x-amz-id-2':
         'uT8Um7FB5rRC4/thCaLzkdNEVG2xX5tWVXtCm6qNnCCrWCLBWjAo64WGr7Ot1sc1eBsEGlqYDx0=',
        'content-type': 'application/xml',
        'transfer-encoding': 'chunked',
        date: 'Thu, 29 Oct 2020 19:27:00 GMT',
        server: 'AmazonS3' },
     requestId: undefined,
     attempts: 1,
     totalRetryDelay: 0 } }

Then I set the region back to us-west-2 and I continued to get a 404 back. But this is where It gets really weird: ALL buckets that do not exist now return a 404 for me. I can no longer reproduce the error thrown from this code and the sample code posted above is no longer reproducible for me.

[alexforsyth]

Okay so this looks like a caching issue with s3. Not a GA blocker. It looks like the cache gets invalidated on the global endpoint first (us-east-1) and then becomes eventually consistent elsewhere. To make this work immediately force your request to go to us-east-1

[trivikr]

Verified that the HTTPResponse remains the same in v3 after bucket deletion is successful.
This could be because v2 is calling us-east-1 endpoint while calling headBucket, as we use waiter from v2. The waiters are not supported in v3 yet.

    "@aws-sdk/client-s3": "1.0.0-rc.3",
    "aws-sdk": "2.782.0"

Code

const AWS = require("aws-sdk");
const { S3 } = require("@aws-sdk/client-s3");

(async () => {
  let response;
  const region = "us-west-2";
  const Bucket = `test-bucket-${Math.ceil(Math.random() * 10 ** 10)}`;

  const logger = { debug: console.log };
  const v2Client = new AWS.S3({ region });
  const v3Client = new S3({ region, logger });

  await v2Client.createBucket({ Bucket }).promise();
  await v2Client.waitFor("bucketExists", { Bucket }).promise();

  response = await v3Client.headBucket({ Bucket });
  // console.log(`v3 headBucket: ${JSON.stringify(response, null, 2)}`);

  await v2Client.deleteBucket({ Bucket }).promise();
  await v2Client.waitFor("bucketNotExists", { Bucket }).promise();

  // try {
  //   response = await v2Client.headBucket({ Bucket }).promise();
  //   console.log(`v2 headBucket: ${JSON.stringify(response, null, 2)}`);
  // } catch (e) {
  //   console.log(`v2 Error:`);
  //   console.log(e);
  // }

  try {
    response = await v3Client.headBucket({ Bucket });
    // console.log(`v3 headBucket: ${JSON.stringify(response, null, 2)}`);
  } catch (e) {
    // console.log(`v3 Error:`);
    // console.log(e);
  }
})();

The global s3 client proposal will have fix this issue: #1807. Change this to documentation as we need to provide more detailed explanation of what happens under the hood.
