the role entity in the grant entity is invalid

[yuyushao]

已有用户，之前登录正常，突然登录开始报错：
[2024/08/05 07:24:40.986 +00:00] [INFO] [rootcoord/root_coord.go:950] ["failed to list databases"] [traceID=036a37b004e8a9f6171f9276d1c02ba5] [msgID=451632871754170374] [error="the role entity in the grant entity is invalid"]

尝试了以下方式重建授权：
1、user 和角色名 及权限完全一致 -- 失败，报一样的错误
2、user 和权限一致，角色名改名 -- 失败，报一样的错误
3、user改名，角色名 及权限完全一致 -- 成功。

请问可能什么问题导致的？谢谢~

Wait @SimFG to comment.

You can try to output all the role names. From the error message, it seems that the role name is not valid.

3. what is the code user access milvus?
