Description

After deleting a SortedSet the behavior for ZRANGE differs from native Redis.

 

Reproduction Steps:

Add some data to a SortedSet:

• ZADD leaderboard 1 "one"
• ZADD leaderboard 2 "two"

Delete the SortedSet with the key "leaderboard":

• DEL leaderboard

Now perform a ZRANGE command on the deleted key

ZRANGE leaderboard 0 10

 

Native Redis returns "(empty array)" where as we return "

"(error) ERR The server had an internal error please try again".

 

The same behavior occurs even if the SortedSet never existed.  For example:

ZRANGE nonexistent 0 10 will also result in 

"(error) ERR The server had an internal error please try again".
