cc @thomasst , any thoughts on this? 😄

The fix would probably be to use Redis functions for Redis 7.0 and above, because they're directly callable by providing keys and argv in the call itself using FCALL <func_name> <keys> <argv>

I have not played around with Redis 7 but that looks good. The way we're doing it currently is a hack.

``Hi,
For information, we encountered the same problem with redis 6.2.6. We also have redis databases in version 6.2.5, and no problems with theses databases.
So i think the problem is on redis >= 6.2.6

Code that create problem for us is :

string.startswith = function(self, str) 
    return self:find('^' .. str) ~= nil
end

And we solved it by creating our own function (no so good... but it works)

local function string_start_with(str, startwith)
    return string.find(str,'^' .. startwith) ~= nil
end
