aws-sdk-client-mock dependency is out of date with aws s3 client types

Problem

I tried updating @aws-sdk/client-s3 and came across some test failures related to types with aws-sdk-client-mock mock client. After looking at the package.json of the mock library, I noticed it is extremely out of date with its aws dependencies:

aws-sdk-client-mock@4.1.0

 "devDependencies": {
    "@aws-sdk/client-dynamodb": "3.363.0",
    "@aws-sdk/client-s3": "3.363.0",
    "@aws-sdk/client-sns": "3.363.0",
    "@aws-sdk/client-sqs": "3.363.0",
    "@aws-sdk/lib-dynamodb": "3.363.0",
    "@aws-sdk/util-dynamodb": "3.363.0",
    "@smithy/types": "1.1.0",
    "typedoc": "0.25.13"
  },

We are trying to update from @aws-sdk/client-s3 version 3.873.0 to 3.884.0 and @smithy/node-http-handler from 4.1.1 to 4.2.0.

Potenital Solutions

• Fork aws-sdk-client-mock update the dependencies and submit a PR.
• Still fork and maintain our own version of this repo
• Replace the s3 client all together with options such as:
  • s3mini
  • aws-lite

After digging around some more, it turns out the conflict was between nested @smithy/types within node-modules causing mismatched type issues. This is because some components of the smithy libraries still try to use version 4.3.2 of the types library while other packages moved on to 4.4.0 which was released 5 days ago as of this post. Adjusting the yarn.lock to point all uses of 4.3.2 to use the new minor version has fixed this issue.

yarn.lock fix:

"@smithy/types@npm:^4.3.2, @smithy/types@npm:^4.4.0":
  version: 4.4.0
  resolution: "@smithy/types@npm:4.4.0"
  dependencies:
    tslib: "npm:^2.6.2"
