Error searching for documents: 42702 column reference "id" is ambiguous It could refer to either a PL/pgSQL variable or a table column

Describe the problem/error/question

I’m working to setup a LLM/RAG system and I receive the error: Error searching for documents: 42702 column reference “id” is ambiguous It could refer to either a PL/pgSQL variable or a table column.

This is after data is put into my documents table. I’m assuming it is because my two tables for documents and chat history both have an ID field …and I’m doing wrong.

I’m happy to grab any additional information to help you help me

I’ve been working on this for a few days and I’m really stuck.

What is the error message (if any)?

42702 column reference “id” is ambiguous It could refer to either a PL/pgSQL variable or a table column.

So, I did not find the answer to this, but removing and setting up my Supabase database all over again seems to have resolved the issue.

My guess is that I did something while building things that did something to the database.

…user error.
