I downloaded the mod for the new 1.21 update and it has everything in the mod it usually does except the inventory cable connector that attaches to the chest to do the transfer of items to the terminal. Is someone able to look further into this?

The 1.21 version is a rewrite, the cable connectors isn't in the game right now, it will be added back in a future update.

Here are the errors related to this issue from my Fabric 1.21-0.15.11 server. Log created at server start on 22-Jun-2024.
