Issue with Google Gemini API RAG Vector Database After n8n Update (Stuck on “Waiting to execute…”)

Questions

Hi,

There seems to be an issue with the new version of n8n.

I’m having a problem connecting and creating a RAG vector database using the Google Gemini API. I’ve done this before and I know exactly how to set it up, but after updating n8n it stopped working.

On another account I was still using an older version (two versions behind) and everything worked correctly there. I copied the exact same settings into the newer version of n8n, but unfortunately it does not work.

For testing purposes, I updated the older version where the connection was still working, and immediately after the update it stopped working as well. I didn’t change anything — I only performed the update.

The workflow stays stuck on “Waiting to execute…”.

I’ve spent around 10 hours trying to debug this, assuming the issue was on my side, but it looks like something is not working properly in the new version of n8n.

This appears to be a known issue with the Google Gemini API integration after recent n8n updates. The “Waiting to execute…” state suggests the API connection isn’t being properly initialized.

Try these steps:

1. Check your n8n logs for any Gemini-related errors

2. Temporarily downgrade to the previous working version if possible

3. Report the issue on GitHub with your workflow JSON and logs

The team is likely already working on a fix, but sharing your specific case will help them resolve it faster.
