The root case is we use follower read to read data and the follower's region is still in flashback state(caused by #43149). This is not a serious bug, we could wait a second to read data.

Should fixed by tikv/tikv#14859, close it

Seems still have follow read problem, reopen it.

@Defined2014
Friendly ping, Is there a related client-go issue and are you still following it?

[Defined2014]

No further news, maybe we could close this until it happened again. @cfzjywxk
