Request error `Premature close` when using API

### Confirm this is a TypeScript library issue and not an underlying Cloudflare API issue

- [x] This is an issue with the TypeScript library

### Describe the bug

Getting error when using `cloudflare.pages.projects.edit`:

```
FetchError: Invalid response body while trying to fetch https://api.cloudflare.com/client/v4/accounts/***/pages/projects/: Premature close
at Gunzip. (/home/runner/work//node_modules/node-fetch/lib/index.js:400:12)
at Gunzip.emit (node:events:521:24)
at emitErrorNT (node:internal/streams/destroy:170:8)
at emitErrorCloseNT (node:internal/streams/destroy:129:3)
at process.processTicksAndRejections (node:internal/process/task_queues:90:21) {
type: 'system',
errno: 'ERR_STREAM_PREMATURE_CLOSE',
code: 'ERR_STREAM_PREMATURE_CLOSE'
}
```

### To Reproduce

Use `cloudflare.pages.projects.edit` in Node 24.17.0

### Code snippets

```TypeScript

```

### OS

Ubuntu

### Runtime version

Typescript 6.0.3

### Library version

v6.4.0

Start by reproducing cloudflare.pages.projects.edit with Node 24.17.0, then trace the request and response handling associated with the Premature close error in the stack trace. Done means the edit request completes without ERR_STREAM_PREMATURE_CLOSE and the behavior is covered by a regression check.
