local im = peripheral.find("inventoryManager")
local cb = peripheral.find("chatBox")
if not im then error("inventoryManager not found") end
if not cb then error("chatBox not found") end
local filter, match = false, false
local tagFilter = {"forge:ores", "forge:raw_materials"}
local function chatListener()
while true do
local event = { os.pullEvent("chat") }
if event[3]:lower() == "ore on" then
filter = true
cb.sendMessageToPlayer("ORE ON", event[2])
elseif event[3]:lower() == "ore off" then
filter = false
cb.sendMessageToPlayer("ORE OFF", event[2])
end
end
end
local function pushItems()
while true do
if filter then
myInv = im.getItems()
for slot, item in pairs(myInv) do
for _, tag in pairs(item.tags) do
for k, v in pairs(tagFilter) do
if string.find(tag, v) then
match = true
break
end
end
end
if match then
im.removeItemFromPlayer("UP", item.count, slot)
match = false
end
end
end
os.sleep(10)
end
end
parallel.waitForAny(chatListener, pushItems)

Answer 1

The problem is that item or item.tags may be nil. You need to check this before calling pairs.
This should work:
while true do
if filter then
myInv = im.getItems()
for slot, item in pairs(myInv) do
if item~=nil then if item.tags~=nil then
for _, tag in pairs(item.tags) do
for k, v in pairs(tagFilter) do
if string.find(tag, v) then
match = true
break
end
end
end
end end
if match then
im.removeItemFromPlayer("UP", item.count, slot)
match = false
end
end
end
os.sleep(10)
end
end
Also, you should know that the Lua APIs for these mods change from version to version, and so you shouldn't be surprised if an old program stops working. You can check the official Advanced Peripherals wiki here, and although it isn't perfect, it is very helpful in situations like these. Finally, if you're having trouble with CC, you can always just open up a new world and test any program you like.
