Hey! For `curl pass file object`, your command is solid. Just make sure the field name matches what the server expects. If they want `"attachment"` instead of `"file"`, do this:
```bash
curl -F "attachment=@path/to/file.json" https://example.com/upload
```
Also, if you’re dealing with JSON, you can specify the MIME type like others mentioned. If you’re still having trouble, try using `-v` to see the full request and response.
```bash
curl -F "attachment=@path/to/file.json" https://example.com/upload
