Hi @hlf2016, thanks for your feedback, it should be related to this issue:https://github.com/apache/incubator-kvrocks/pull/930. Kvrocks will return an empty bulk string(`nil` for redis-cli), you can have a check if you have the empty key name like below:
```
127.0.0.1:6666> get ""
"1"
```
And delete if this key was not expected, then the `nil` will be disappeared.

@hlf2016 I can't get the point and it'd be better to add reproduce steps, or we cannot fix this issue.

@hlf2016 It means this key exists and it's NOT a string type, you can use `type ""` to inspect the value type.

Yes I once tried this but it made no effects
So any other characters can lead to this ?
