local config = {
    pos1 = getCreaturePosition(cid),
    bushId = 1285,
}

function onSay(cid, words, param, channel)
    if(param == '') and
        getTileItemById(config.pos1, config.bushId).uid <= 0 then
    doTileAddItemEx(config.pos1, config.bushId)
    end
        return true
    end

and i do get tile not found error, why?

Because there is no uid that is less then or equal to 0 ( <= )

if(param == '') and getTileItemById(config.pos1, config.bushId).uid <= 0 then

Plus you can't call getCreaturePosition(cid) in a table outside of an interface like onSay

local config = { pos1 = getCreaturePosition(cid), bushId = 1285, }

Cid is nil when defined this way. Define it inside your function instead.

If you use getTileItemById(pos, itemid).uid, it will return 0 if the item with that itemid isn't there on that position, if the item is there, it will return the uniqueid of the item.
So you can use this to check if an item with a certain itemid is on a certain position.

If you use getTileItemById(pos, itemid).uid, it will return 0 if the item with that itemid isn't there on that position, if the item is there, it will return the uniqueid of the item.
