你將會改而得到文字版：

```
Validation errors:
Field: ('path', 'item_id'), Error: Input should be a valid integer, unable to parse string as an integer
```

### 覆寫 `HTTPException` 的錯誤處理器 { #override-the-httpexception-error-handler }

同樣地，你也可以覆寫 `HTTPException` 的處理器。

例如，你可能想在這些錯誤時回傳純文字而非 JSON：

		queueStore = store.NewQueueStore[event.Event](queueDir, args.QueueLimit, event.StoreExtension)
		if err := queueStore.Open(); err != nil {
			return nil, fmt.Errorf("unable to initialize the queue store of NATS `%s`: %w", id, err)
		}
	}

	target := &NATSTarget{
		id:         event.TargetID{ID: id, Name: "nats"},
		args:       args,
		loggerOnce: loggerOnce,

		}

		// Use the user provided ID here.
		resourceID += roleID
	}

	roleArn, err := arn.NewIAMRoleARN(resourceID, serverRegion)
	if err != nil {
		return args, config.Errorf("unable to generate ARN from the plugin config: %v", err)
	}

	args = Args{
		URL:         u,
		AuthToken:   authToken,
		Transport:   transport,
		CloseRespFn: closeRespFn,
		RolePolicy:  rolePolicy,

	globalBatchJobsMetrics.save(job.ID, ri)
	// persist in-memory state to disk.
	batchLogIf(ctx, ri.updateAfter(ctx, api, 0, job))

	if err := r.Notify(ctx, ri); err != nil {
		batchLogIf(ctx, fmt.Errorf("unable to notify %v", err))
	}

	cancel()
	return nil
}
