终端下创建tag index时遇到 [ERROR (-8)]: invalid parm! 错误。

终端显示如下:


(root@nebula) [full_kg]> CREATE TAG IF NOT EXISTS VTag(name string);
Execution succeeded (time spent 1326/1717 us)

(root@nebula) [full_kg]> describe tag VTag;
+--------+----------+-------+---------+
| Field  | Type     | Null  | Default |

metad日志如下:

metad代码段(链接):

...

对字符串类型的属性创建索引要指定长度。文档:
