### Search before asking

- [x] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar.

### Version

2.0.2

### Describe the bug and provide the minimal reproduce step

在非集群部署的IoTDB实例中，向表模型插入数据会出现错误

There are no available SchemaRegionGroup RegionGroups currently, please use \"show cluster\" or \"show regions\" to check the cluster status


### What did you expect to see?

即使是文档中的示例代码，也没有返回预期的成功

### What did you see instead?

There are no available SchemaRegionGroup RegionGroups currently, please use "show cluster" or "show regions" to check the cluster status

### Anything else?

_No response_

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Start by reproducing the table-model insert failure on a non-clustered IoTDB 2.0.2 instance using the documentation example, then inspect the path associated with the SchemaRegionGroup error. Done means the example inserts successfully in non-cluster mode without reporting that no SchemaRegionGroup RegionGroups are available.
