How to tell when datastores fail?

Recently I was testing my game, and the datastores just happened to fail. They gave me a 500 error code, and then my GetAsync() request dropped. Anyways, my datastores use UpdateAsync(),so I thought this would not be a problem as it would just not save the users play session. However, when the GetAsync() request failed it set my collectibles, coins, etc. all to 0. Then, when I left the game saved all of my stats as 0. So, I am basically looking for a way to tell if a GetAsync request fails. If it does, I would like to kick the player WITHOUT saving their data. I know how to kick them/not save the data, I am just lost on how to tell if my GetAsync() request fails.

I would appreciate any help. Thanks in advance!

maybe this?

local s = pcall(function() -- s == success
--code
end)

I have wrapped it in a pcall, I am not 100% certain on the way that success works though. Is success true until an error occurs, or is it false until the pcall finishes?

I know that the “success” value is false when an error occurs.
If error doesn’t occur, then it’s true.

s = pcall(function() 
print(nil+2) 
end) 

print(s) -- false

error: attempt to perform arithmetic (add) on nil and number

pcall runs until an error is occurred, at which point it will break out, returning false and the error

local x = 0

pcall(function()
  x += 1
  error()
  x += 1
end)

print(x) --> 1

Roblox will handle critical DataStore errors for you, remember, if GetAsync throws an error, its likely something went wrong on Roblox’s end.

Dude it’s easy. Pcall has handled it for you.

local success,errmsg = pcall(function()
GetAsync(data) -- ur GetAsync code here
end)

if not success then
warn("big chungus alert, Roblox trashy datastore failed!")
end
