* ZRem is a method belonging to ZSetStructure that removes a member from a ZSet. Parameters: - key (string): The key of the ZSet. - member (string): The member to be removed. Returns: - error: An error if the operation fails. The ZRem method checks for a non-empty key, retrieves the corresp

(key string, member string)

the function will return the corresponding error.
