Subject: Gemini Node Issue: "Resource not found" - Only "2.5-flash" available in dropdown instead of "1.5"

Questions

Hi everyone,
I’m facing a persistent issue with the Google Gemini (PaLM) node. My project is an educational platform designed to assist students by processing PDF and Word documents.
The Problem:
I keep getting a “Resource not found” error. What’s strange is that in the Model selection dropdown, I only see options for “gemini-2.5-flash” and not the stable “1.5-flash” version. When I try to manually type gemini-1.5-flash or use the available 2.5-flash from the menu, the node fails.
What I’ve Checked:

  1. Model Selection: The dropdown menu is showing “2.5-flash” which seems incorrect as Google hasn’t officially released a 2.5 version. Is this a bug in the current n8n node version?
  2. Binary Data: The download node is working, but Gemini sees the input as “empty”.
  3. Credentials: Using Google Gemini(PaLM) API.
    Questions:
  • Is the “2.5-flash” option in the dropdown a known issue?
  • How can I force the node to recognize the correct 1.5-flash resource for documents?
    I have attached screenshots of the dropdown menu showing the “2.5-flash” option. Any help would be greatly appreciated!
