Each yielded item is encoded as JSON and sent in the `data:` field of an SSE event.

If you declare the return type as `AsyncIterable[Item]`, FastAPI will use it to **validate**, **document**, and **serialize** the data using Pydantic.

## Troubleshooting

### Common Migration Issues

#### Issue: Import fails with "Invalid format"

**Solution**:
- Ensure NDJSON files have one valid JSON object per line
- Check for UTF-8 encoding
- Validate JSON syntax with `jq`:
  ```bash
  cat documents.ndjson | jq empty
  ```

#### Issue: GSA XML import creates no configurations

**Solution**:
- Verify XML structure matches GSA export format

			ClientCert: env.Get(clientCertEnv, kv.Get(target.WebhookClientCert)),
			ClientKey:  env.Get(clientKeyEnv, kv.Get(target.WebhookClientKey)),
		}
		if err = webhookArgs.Validate(); err != nil {
			return nil, err
		}
		webhookTargets[k] = webhookArgs
	}
	return webhookTargets, nil

    }
