I can't find the langchain node in my selfhosted n8n

Describe the problem/error/question

I’m running a selfhosted n8n version:1.109.2, and I can’t find the n8n-node-langchain there; and before I’m using the ai-beta version and I’m pretty sure i got langchain node there. and also tried installing the node from the Community nodes page and it replies : Error loading package “n8n-nodes-langchain” :The specified package does not contain any nodes. and i’m totally giving up on this. and could anyone help me with this? or do I have to stay in 77 versions back at ai-beta version?

What is the error message (if any)?

Information on your n8n setup

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

I assume you are talking about

@n8n/n8n-nodes-langchain
from https://www.npmjs.com/package/@n8n/n8n-nodes-langchain

and this image: https://hub.docker.com/layers/n8nio/n8n/ai-beta/images/sha256-b312c79d41953f24e19e0b1391eaa57bf85828fbc29b789b0156599d1aa75260

If so, I see that the ai-beta image is pushed over a year ago and the npm package is somewhat unmaintained (the github link is dead for once).
