Using the vector store tool

[Joachim_Brindeau]

Hello,

I am stuck trying to use the Vector Store Tool.
I read this post by @Jim_Le but maybe I am missing something.

Here is my workflow:

I have managed to insert everything into my vector database but I can’t figure out how to use it now.

Here is the issue I am facing:

I hope someone can help me!

Thanks a lot

It looks like your topic is missing some important information. Could you provide the following if applicable.

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

Hey @Joachim_Brindeau

I think you might have come across a possible bug. I feel you may be running into version compatibility issues of the node if you’ve copied from somewhere?

Can you try:

1. Recreate using the nodes sidepanel (no copy+paste workflow). This should ensure you’re working with compatible versions of the nodes.
2. Switch to the tools agent instead rather than the conversational agent. Tools agent has been the default from a few releases now and should do a better job with tools.

I tried both agents, will try now creating from scratch.
Thank you for your help!!

Unfortunately I get the exact same result building from scratch…

Here is some info about my setup:

Debug info

• n8nVersion: 1.54.1
• platform: docker (self-hosted)
• nodeJsVersion: 20.15.0
• database: postgres
• executionMode: regular
• concurrency: -1
• license: community
• consumerId: unknown

Ah ok, I just updated to 1.54.1 and yes, it’s currently breaking from me as well.
Would advise downgrading temporarily to 1.53.0 which works for certain.

[Joachim_Brindeau]

Thank you so much for checking it!
I hope it’ll be fixed soon, going to downgrade in the meantime.

AI chat with different steps and vector stores

Hello! I have a question regarding building an AI chat. I try to suggest classification of business ideas using a list of terms. My list is made of 10k terms that I plan on bumbing to 80k terms. They are categorized in 45 categories. I have managed to: make a tools agent that outputs the JSON of the categories (from vector store A) to filter from (let’s call it Output A). make a tools agent that outputs the final selection of terms (from vector store B), filtering on a metadata that match…
