Lua if string contains?

[Xagul]

Hello I am trying to simply determine if a string contains somthing and for some reason it will not work, it keeps sending me the error:

[6:45:22.246] data/actions/scripts/tools/unid.lua:5: bad argument #1 to 'find' (string expected, got nil)

I am currently using this:

itemdesc = getItemAttribute(itemEx.uid, "description")
	
	if(string.find(itemdesc, 'hello') ~= nil) then
		doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "true")
	else
		doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "false")
	end

Put after itemdesk = ....

if itemdesc == nil then itemdesk = '' end

well the problem I am having is the item does have a description, the item description is infact the word "hello" but even then it still throws me that error =\

data/actions/scripts/tools/unid.lua:5: bad argument #1 to 'find' (string expected, got nil)

Argument #1 in the string.find function is 'nil'.
Means itemdesc IS nil.

itemdesc = getItemAttribute(itemEx.uid, "description")

Something is wrong there probably, I think "description" isn't correct.
