Solved Need help with error handling (Lua)

I have a plugin that is using PLUGIN:OnRunCommand to catch commmands admins are using and log them. I got the plugin working great, but I have a side effect. The plugin goes to grab the player ID, but if a player doesn't issue the command, it spits out this code:

Code:

[Oxide] 3:06 PM [Error] Failed to call hook 'OnRunCommand' on plugin 'Admin Anti-Abuse'
File: adminanticheat.lua Line: 26 attempt to index field 'connection' (a nil value):

[Oxide] 3:06 PM [Info] [BetterLoot] BetterLoot: Refreshed 6 containers (0 destroyed)

Is there a way to stop these errors from occurring? I tried using pcall() to catch errors, but that didn't work. Here is the problem code:

Code:

function PLUGIN:OnRunCommand(arg)
local player = arg.connection.player
local steamID = rust.UserIDFromPlayer(player)
local msg = arg:GetString(0, "text")
local name = player.displayName
local msgedit = explodeString(msg)

Thanks.

 

if not arg.connection then return end

 

Thanks, that did it
