Use the following tsup config:

{
  "clean": true,
  "sourcemap": true,
  "watch": false,
  "silent": true,
  "entry": [
    "src/index.ts"
  ],
  "dts": {
    "resolve": true
  },
  "tsconfig": "tsconfig.build.json",
  "outDir": "lib",
  "format": [
    "cjs",
    "esm"
  ],
  "shims": true,
  "target": "node22.16.0"
}

build:

tsup

Explodes with error:

RollupError: "SmithyRpcV2CborProtocol" is not exported by "../../node_modules/.pnpm/@aws-sdk+core@3.946.0/node_modules/@smithy/core/cbor.d.ts", imported by "../../node_modules/.pnpm/@aws-sdk+core@3.946.0/node_modules/@aws-sdk/core/dist-types/submodules/protocols/cbor/AwsSmithyRpcV2CborProtocol.d.ts".

Additional Information/Context

I've created a minimal reproduction repository:

https://github.com/moltar/aws-sdk-issue-7567

Steps to reproduce:

1. Clone the repo
2. pnpm install
3. pnpm build

The build will fail with:

RollupError: "SmithyRpcV2CborProtocol" is not exported by "node_modules/.pnpm/@aws-sdk+core@3.946.0/node_modules/@smithy/core/cbor.d.ts"

Key requirement: the SDK package must be a devDependency so that tsup attempts to bundle the types (with dts.resolve: true).
