[Bug]: No error raised when the rootPath is wrong

[zhuwenxing]

Current Behavior

My Milvus is deployed by helm, so the default rootPath is by-dev.

But I refer to the following command, set the rootPath as instance name.

However, it does not raise any errors. It can not show any info when I type show collections(already create many collections).

This makes me confused: It does not work, but there is no error happened.the

Expected Behavior

Good point. Currently Birdwatcher cannot detect rootPath was a valid one or not.
We could add a cheap check at least that whether rootPath prefix exists or not
