In my self hosted n8n it won't load the previous executions, it is working on my cloud hosted n8n. Has anyone solved this issue with the self hosted n8n setup. my self hosted setup is running n8n version 1.76.1 at the moment.

I have copied the workflow from Nate's "Step by Step: RAG AI Agents Got Even Better", which worked great. I'm now making a change where I am swapping out the "Superbase vector store" with a "Postgres vector store”, I have the vector store working , adding files working and chatting with the agent working.. However, I’m encountering an issue with deleting rows from the “vectors” table in the Postgres vector store. Specifically, I want to delete selected rows from the Postgres vector store data when updating a Google Doc that’s already in the vector store. This process involves creating new vectors from the latest version of the Doc and removing old vectors related to the previous version. I have been trying to setup the Postgres delete node but, I keep getting an error when attempting to find and delete the correct rows. Any assistance in how to configuring n8n to delete rows from a Postgres vector store would be greatly appreciated.
