Describe the bug

I'm upgrading AWS SDK using Renovate, and currently, it had raised a PR to upgrade:

• @aws-sdk/client-quicksight
• @aws-sdk/client-sts
• @aws-sdk/util-arn-parser

All deps are fixed versions, and are being upgraded from 3.797.0 to 3.840.0.

And now I am getting the following error during builds:

Error [ERR_WORKER_OUT_OF_MEMORY]: Worker terminated due to reaching memory limit: JS heap out of memory
    at [kOnExit] (node:internal/worker:314:26)
    at Worker.<computed>.onexit (node:internal/worker:230:20)
Emitted 'error' event on Worker instance at:
    at [kOnExit] (node:internal/worker:314:12)
    at Worker.<computed>.onexit (node:internal/worker:230:20) {
  code: 'ERR_WORKER_OUT_OF_MEMORY'
}

The building is done with tsup, which wraps esbuild under the hood.

I know that QuickSight types are insanely complex, so it could be due to that. However, given that esbuild is an extremely popular tool within the AWS CDK community, I think this should be explored further.

This issue is definitely very isolated, as other Renovate PRs get built and merged easily, and the mainline branch builds just fine under the same conditions; it's only this upgrade PR that is failing.

I'm more than happy to give you more context for debugging this; just let me know what you'd like to see.

Thanks.

I encountered this error while running the repro repo from moltar/aws-sdk-qs-bundle.

As mentioned in #7188, this appears to be caused by some sort of bug in tsup. At this point, I believe this can only be fixed in tsup, and not here in the AWS SDK.

"dts": {
  "resolve": false
},

works around the issue.

Hi @moltar - checking in here.

After reviewing this issue with our team and checking previous comments, we've identified that this is likely caused by a known bug reported in tsup egoist/tsup#920. If the problem still occurs in a non-tsup environment, please let us know and we'll investigate further.
