reply type 6 is an error reply. There are only a few reasons for this to happen when executing TYPE, like Redis is loading from a dump or a slave is serving stale data.

redis-cli should probably handle this more gracefully.

But the same error when I shutdown all slave

This was even hard to trigger :-) Since normally it fails during the DBSIZE call at startup, or often in the SCAN call. However I can trigger it. Fixing... thanks for reporting.

Hi, Is this problem solved?

reids version : redis-cli 3.2.8

Invalid reply type (6) for TYPE on key
