**Owned by** [Build with your coding agent](https://services.dev/docs/start/agents.md): the page that explains what this gate holds.

## What check says

```txt title="npx services.dev check"
  ✗ An agent couldn't order, wait for and accept a job. Run npx services.dev dev and read its job. It stopped at: draft: Cannot read properties of undefined (reading 'map').
    https://services.dev/docs/reference/check/agent_cannot_buy
✗ 1 to fix
```

## The failing file

```ts title="services/translation.ts"
import { Service } from 'services.dev'

export default Service({
  name: 'Translation',
  input: { document: 'file', to: 'language: a BCP 47 tag, such as fr-CA' },
  output: { document: 'file' },
  deliver: async ({ document, to }) => {
    const pages = document.pages.map(page => page.text)
    return { document: { name: `${document.name}.${to}`, text: pages.join('\n') } }
  },
  price: 49,
})
```

## The fix

```diff title="git add -A && git diff --staged"
diff --git a/services/translation.ts b/services/translation.ts
index 820ccb4..e7fd1f6 100644
