I've upgraded StackExchange.Redis nuget package to the latest version 2.6.45 and I've noticed that my previously working Lua script is no longer accepted at startup by Stack Exchange library. The exception thrown is
System.ArgumentException: Count not parse script: [...]

local MessageStoreAPI = {}
MessageStoreAPI.confirmPendingDelivery = function(smscMessageId, smscDeliveredAt, smscMessageState)
local messageId = redis.call('hget', "smId:" .. smscMessageId, 'mId')
if not messageId then
return nil
end
-- delete pending delivery
redis.call('del', "smId:" .. smscMessageId)
local mIdK = 'm:'..messageId
local result = redis.call('hsetnx', mIdK, 'sState', smscMessageState)
if result == 1 then
redis.call('hset', mIdK, 'sDlvAt', smscDeliveredAt)
redis.call('zrem', "msg.validUntil", messageId)
return redis.call('hget', mIdK, 'payload')
else
return nil
end

The very same script is working when using a previous version of StackExchange.Redis. Any hint on what's going on? The exception's message is not very helpful at pointing the error.
