Debug.traceback() not showing the traceback

[rogeriodec_games]

I have this function to intercept errors:

game:GetService("ScriptContext").Error:Connect(function(Error)
	warn(Error)
	print(debug.traceback())
end)

An error is occurring in a function that is at the 4th level of the call stack.

However, debug.traceback() is not showing the stack, just the current line of the print(debug.traceback()) statement itself:

What could be wrong?

Try this:

function DebugTest(Err)
  warn(Err)
  print(debug.traceback())
end

game:GetService("ScriptContext").Error:Connect(DebugTest)

Results:

Can you try using the second “level” parameter and see of that helps? I do believe that the default is level 1 so it just returns the first instance of the traceback call.

@Anurag_UdayS @3gData tks but both suggestions make no difference.
I’ve open a bug report:

Debug.traceback() won't work inside ScriptContext

Reproduction Steps Run this: local function c() print('c') error('MyError') end game:GetService("ScriptContext").Error:Connect(function(err) warn(err) print(debug.traceback()) end) c() Expected Behavior debug.traceback() should show the entire traceback, like: Stack Begin Script 'Workspace.Script', Line 3 - function c Script 'Workspace.Script', Line 11 Stack End Actual Behavior debug.traceback() is showing only it’s current line: Workspace.Script:8 Issue Area: Engine Iss…

Hello. I figured out the issue. It is because the connected function is not a part of the thread encountering the error, it is a completely new function created within and connected to the event of game:GetService("ScriptContext").Error. You are advised to use the second parameter of the Error EventEmitter. It is the default way to get the stack trace.

game:GetService("ScriptContext").Error:Connect(function(message, trace, script)
	print(script:GetFullName().." errored!")
	print("Reason: "..message)
	print("Trace: "..trace)
end)

Hope this helps!
