Missing "Simple Memory" node in n8n v2

What is the problem? After migrating to version 2, I have noticed that the Simple Memory node is unavailable in my installation. While my current workflows are executing correctly and without errors, I am unable to locate or add this specific node to manage chat history in new or existing sequences. Technical Context: Status: Workflow execution is stable. Problem: Node library does not list “Simple Memory”. Goal: Implement chat history persistence using the standard memory node. [i…

hi @Osama_Al-Ani , good day!

If your n8n instance is running in queue mode, this is expected. The Simple Memory node is not suitable for active production workflows in queue mode because executions can run on different workers, so n8n cannot guarantee the same in-process memory is used each time.

For a VPS setup, I would recommend using a persistent memory node such as Redis Chat Memory or Postgres Chat Memory, depending on what you already have available.

Hi @Osama_Al-Ani — check your env for EXECUTIONS_MODE=queue. if you set that on your VPS but only run one instance, you dont actually need queue mode. unset it (or set EXECUTIONS_MODE=regular) and restart, Simple Memory will show back up in the node picker.
