Title: Attempt to call method 'find' a nil value
Post by: Sir Klutch on April 05, 2017, 07:18:52 PM

Hello, I am receiving this error from a custom ulx motd menu everytime you join the server.

Code: [Select]

[ERROR] addons/ulx/lua/ulx/modules/cl/motdmenu.lua:78: attempt to call method 'find' (a nil value)
  1. fn - addons/ulx/lua/ulx/modules/cl/motdmenu.lua:78
   2. func - addons/ulib/lua/ulib/client/cl_util.lua:22
    3. unknown - lua/includes/extensions/net.lua:32

The user who wrote this code is MrPresident. The code can be found here;
https://forums.ulyssesmod.net/index.php/topic,6113.msg29952.html#msg29952

The error is within

Code: [Select]

function ulx.rcvMotd( isUrl_, text )
isUrl = isUrl_
if not isUrl then
ULib.fileWrite( "data/ulx_motd.txt", text )
else
if text:find( "://", 1, true ) then
url = text
else
url = "http://" .. text
end
end
end

Help would be greatly appreciated!

This code is 4 years old. It's not surprising that it doesn't work.

What exactly are you trying to do?

Fix the error. Everything works as intended to.

You fixed it? What did you do to fix it?

Lol, sorry if you misunderstood. I did not fix the error, you asked 'What exactly are you trying to do?' and I said fix the error. I could probably gut it and everything would be fine. Also, I could perhaps add a conditional to make sure text exists, is a string, and has a .find method

Code: [Select]

if not ( ( text ) and ( type( text ) == "string" ) and ( text.find) ) then return end
Would most likely fix the error, yes. Although I cannot find where the function is being called.

I went ahead and gutted it.
