I am using this code inside a chat handler script. The POST call returns (or I can force it to fail) but it looks like the `player` object has gone out of scope.
```if msg == "test" then
player:SendBroadcastMessage("still in scope 1")
HttpRequest("POST", "http://localhost:9000/go", jsonString, "application/json", function(status, body, headers)
player:SendBroadcastMessage("still in scope 2")
print(body)
if(body == nil or body == '') then
player:SendBroadcastMessage("Failed")
else
player:SendBroadcastMessage("Success")
end
end)
end
```
Any thoughts?

Yes, it's a callback function, the player doesn't exist in that context

```Lua
local function OnResponse(status, body, headers)
-- This is a different function, player is not a variable. When you use this inline, you are just lucky if the player object even exists..
player:SendBroadcastMessage("still in scope 2")
print(body)
if(body == nil or body == '') then
player:SendBroadcastMessage("Failed")
else
player:SendBroadcastMessage("Success")
end
end
local function OnChat(event, player)
if msg == "test" then
player:SendBroadcastMessage("still in scope 1")
HttpRequest("POST", "http://localhost:9000/go", jsonString, "application/json", OnResponse)

That is inherently how this works. If the response function is triggered in a later update, ie. not this tick and synchronous, the player object doesn't exist because the parent function context doesn't exist anymore

Calling a userdata object inside an inline callback function is inherently dangerous and unintended and unstable behavior

`playerGuid = player:GetGUID()` followed up later by `newplayer = GetPlayerByGUID( playerGuid )` does the trick safely
