Problem with `netlify-cli`. I created a extremely simple [reproduction repository.](https://github.com/jaredh159/netlify-cli-bug-repro)

I’m using the new `@netlify/functions` first-class typescript support feature. _Love it (except for this problem), by the way, thanks!_

The problem is, I’m importing a dependency, the official AWS S3 client `@aws-sdk/client-s3`, and this is causing `netlify dev` to break. Here’s the relevant code from the repro:

```plaintext
import { Handler } from '@netlify/functions';
import { S3 } from '@aws-sdk/client-s3';

const handler: Handler = async (event) => {
  // Omitted: actually doing something with the S3 Client
  // vvvv--- but this line causes `netlify dev` to break
  const client = new S3({});

  return {
    statusCode: 200,
    body: `Hello world`,
  };
};

export { handler };

```

The error message reported by `netlify-cli` is “ **`Cannot find module 'exports'`** ” (full error message below).

NOTE: the function _builds just fine on netlify and works_, it’s just `netlify-cli` chokes on it.

If I comment out the usage of the `S3` imported function, the problem goes away (I presume because of esbuild tree-shaking or something).

I also made the recommended settings of `esModuleInterop` and `isolatedModules` in the `tsconfig.json` file.

Again, there’s a super simple reproduction here:

Just clone, npm install, and run `npm run dev` to see the issue. Thanks in advance for any help, and again, really love the first-class typescript support! 🙏

Hey @jaredh159,  
Would you mind filing this on the CLI repo? [Sign in to GitHub · GitHub](https://github.com/netlify/cli/issues/new/choose) It’ll get 👀 quicker that way. Also very glad to hear that you’re excited about the Typescript support, I’ll pass that along to the team!

sure, I was wondering when I opened this if that would be a better spot.

[Done.](https://github.com/netlify/cli/issues/2227)
