🗑️ (DEPRECATED) Session ID Selector

The display name says it all: 🗑️ (DEPRECATED) Session ID Selector. This is the pack's original session-picker node, and in current builds you should almost certainly not use it. It still ships because removing a node breaks every saved workflow that references it, but it's a legacy artifact - a leftover from before the Session Memory Reader grew the same functionality built in.

If you're on a fresh workflow, that's the whole article: skip it, use the Reader's dropdown instead, and save yourself a node and a wire.

What it does

In its day it was simple: a dropdown listing every session already on disk plus a [CREATE NEW] option, and a text box for the new session's name. Pick one and it output a session_id string you could feed into the Reader and Writer so all three nodes agreed on which session file to use. That's a genuinely useful job - mismatched session ids are the classic way to write memory into one file and read from another.

But the Reader now embeds the exact same two inputs - existing_session and new_session_name - and it also outputs session_id as one of its three outputs. The picker's whole reason to exist got absorbed. Adding a SessionIDSelector to a modern graph means one more node, one more wire, and zero new capability.

Inputs and output

• existing_session - dropdown of existing sessions, with [CREATE NEW] at the top. Populated when the node loads, so newly created sessions appear after a reload.
• new_session_name - used if you picked [CREATE NEW]; becomes the session id.

The single output, session_id (STRING), is the chosen id, sanitized to safe filename characters. It's a plain string output, so technically you could use it to pick a session for anything that accepts a string - but don't build around it.

Installing it

It ships inside Latentnaut/ComfyUI-Session-Memory, so installing the pack for the Reader/Writer/Feedback Editor brings this along whether you want it or not.

cd ComfyUI/custom_nodes
git clone https://github.com/Latentnaut/ComfyUI-Session-Memory

Restart ComfyUI, or use ComfyUI Manager (search Session Memory). No models, no extra dependencies - the whole pack is one Python file plus a frontend script.

The one case where it's relevant

If you're loading an older workflow that already contains a SessionIDSelector, it still works - the node class is registered and functional, not stubbed out. Leave it in place rather than ripping it out and rewiring, because that's a working graph. Just know that when you build your next workflow from scratch, the Reader's built-in selector is the same thing without the extra node.
