Describe the problem/error/question
Hello everyone, new user here!
I’m implementing an agentic RAG System using Supabase as vector store but randomically I get error with apparent no reason.
In fact if I try back some moments after using the same query it start working again.
What is also annoying me is that since in the Vector usage as tool there is no Error handling possibility it just blows up with no possibility to retry or implement any error flow that I think it should be done to have a robust architecture.
Any idea on why this is happening?
Please find the error I receive
Thank you!
What is the error message (if any)?
