Missing down-leveled declarations (dist-types/ts3.4)

[RomainMuller]

Hello,

The tarball of @aws-sdk/[email protected] has the following types versions declaration:

"typesVersions": {
  "<4.0": {
    "dist-types/*": [
      "dist-types/ts3.4/*"
    ]
  }
}

However the tarball does not contain a dist-types/ts3.4 directory, making this library impossible to use with TypeScript versions earlier than 4.0.

This happened as the script to downlevel types was not being run while building npm artifacts in our new release automation system.

We've fixed that issue in internal scripts, and downlevel types will be released with v3.51.0 expected to be released on Friday 02/11. We've also taken a backlog item to run downlevel script in prepublishOnly script, which we couldn't do in old release automation system because of some limitations.

ToDo: Verify if downlevel types present after v3.51.0 release.

ToDo: Verify if downlevel types present after v3.51.0 release.

Verified that downlevel-types are available in v3.51.0 release of @aws-sdk/client-s3

$ yarn add @aws-sdk/[email protected] --exact

$ ls node_modules/@aws-sdk/client-s3/dist-types 
commands        index.d.ts  pagination  runtimeConfig.browser.d.ts  runtimeConfig.native.d.ts  S3Client.d.ts  ts3.4
endpoints.d.ts  models      protocols   runtimeConfig.d.ts          runtimeConfig.shared.d.ts  S3.d.ts        waiters

However, the the downlevel types are missing in @aws-sdk/types as it's v3.51.0 version was not released because of lack of commits.

$ ls node_modules/@aws-sdk/types/dist-types 
abort.d.ts   command.d.ts      crypto.d.ts       http.d.ts   logger.d.ts      pagination.d.ts  serde.d.ts   signature.d.ts  util.d.ts
client.d.ts  credentials.d.ts  eventStream.d.ts  index.d.ts  middleware.d.ts  response.d.ts    shapes.d.ts  transfer.d.ts   waiter.d.ts

ToDo: Push a commit in all packages so that v3.52.0 is released with downlevel types.
As of now, the workaround is to use v3.49.0 versions with older versions of TypeScript.
