DistributedLock.Redis lua error with keyprefix on redis cluster. #254
Description
The following script will cause an error on some cloud Redis servers:
EVAL if redis.call('get', ARGV[1]) == ARGV[2] then return redis.call('del', ARGV[1]) end return 0
StackExchange.Redis.RedisServerException: ERR bad lua script for redis cluster, all the keys that the script uses should be passed using the KEYS array, and KEYS should not be in expression.
ChatGPT suggests using KEYS[0].
Activity
Redis Key argument use KEYS rather than ARGV.

Likely caused by StackExchange/StackExchange.Redis#2273
Ensure that all lua scripts partition parameters between KEYS and ARGV
