## Browser Upload File

Upload files to a file input element. Programmatically sets the files on an input[type='file'] element. Supports multiple files if the input accepts them. File paths must be absolute paths on the server.

# Async usage
async with OwlBrowser(config) as browser:
    context = await browser.create_context()
    context_id = context["context_id"]
    await browser.upload_file(
        context_id=context_id,
        selector="#element-id",
        file_paths="value"
    )
```

### Node.js SDK

```javascript
import { OwlBrowser } from '@olib-ai/owl-browser-sdk';

// Async usage
const ctx = await browser.createContext();
const contextId = ctx.context_id;
await browser.uploadFile({
    context_id: contextId,
    selector: '#element-id',
    file_paths: 'value'
});
```

## Parameters
