1. Is this request related to a challenge you're experiencing? Tell me about your story.

Since yesterday if I use rerank model by Jina AI the retrieval fails.
It is probably an issue on their side.

The knowledge retrieval node swallows the error and simply returns an empty response as if everything was fine but no documents were found.

A chatbot that relies on RAG cannot afford to stop working without any alarm because the node hides errors under the rug.

Just like LLM node raises exceptions and has retry and raises errors in case the remote API has issues, so MUST be the KB node that is using LLM models under hood

2. Additional context or comments

No response

3. Can you help us with this feature?
