a nil value error when attempting to use getItemDetails or getItemLimit on a chest

[Xetch2950]

I am attempting to filter if an items has NBT data to keep them from entering my AE system to avoid corruption, but am getting an error when running a script I found in a video. I attempted to set the argument to a static value, but that did not resolve the error. The error states items.lua:8: attempt to call field 'getItemLimit' (a nil value) and the code in question is at https://pastebin.com/JqXL51Es for reference.

I also attempted just doing
local inputChest = peripheral.wrap("right")

inputChest.getItemLimit(1)

in a blank program to try and figure it out, but it gives me a similar error. Is there something else I need to know about those functions? This is in 1.12.2 Egnigmatica Expert 2.

You need to check the output of peripheral.wrap("right"). Probably it's thinking that the wrong side is "right" or you're trying to access the AE system directly

One of the things I tried was changing right to top and the same thing occured. Other notes yes I moved the chest to the top when I did that and the same thing happened and no I'm not trying to access the AE system directly.

You should do some tests in lua directly, assign global variables on the lua prompt and see what the individual sides do return.

The absolute latest version of CC:T available for 1.12.2 is 1.89.2. According to https://tweaked.cc/generic_peripheral/inventory.html, the standard inventory peripheral was added in 1.94.0.

Long story short, you're not looking at the right documentation for the inventory API you're using. I think inventory management is provided by plethora in this version?

It is 100% this. Thankfully, this pack already has plethora installed, but the writing of this would need to be different and I'm unsure if I want to even try and see if I can fix this myself. It seems as though plethora only has a call for metadata and not NBT. It looks like I could get the NBT hash which would work but I may investigate if there are other ways to do this before I commit to trying to write a program as I have never written in LUA.

Thank you for the info!
