Chat Node Fails to Retrieve Data from Supabase Vector Store

Problem:

I am extracting content from an uploaded PDF file, splitting it into token chunks, and storing these in a Supabase Vector Store. However, when I query the Chat node for information about the extracted data, it returns an empty array and claims it has no record of the file.

Workflow:

BASHCopied
n8n Info:
---------
* **n8n version:** 1.72.1
* **Database (default: SQLite):**
* **Running n8n via:** Docker
* **Operating system:** Windows

Has anyone encountered this issue or found a solution to ensure the Chat node consults the Supabase Vector Store correctly?
