MessageOut Event

Instead of using the LogService for getting script errors, I recommend using ScriptContext's error event. It gives you a reference to the script object that errored, as well as the stack trace and the error message.

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

(This example was taken from the wiki page for ScriptContext.Error)

You can use this event to see the errors. You can also use the log service, although it might not be enabled right now.
