Use Gemini's fine tuned model in "Gemini Chat Model" node

Describe the problem/error/question

I just fine tuned a Gemini-1.5-flash model and I 'have been trying to use it in my n8n work flow, in the “Gemini Chat Model” node.

Inside the node, I set the “Model” field to {{ "models/tunedModels/my-fine-tuned-models-name" }}.

In the fine-tuned model, I assigned permissions to the project.

When I run the workflow, I get the below error message.

Am I doing something wrong, or is it just not possible to call a fine tuned model from the “Gemini Chat Model” node?

What is the error message (if any)?

Error in sub-node ‘Google Gemini Chat Model‘

Sorry, I have to bump this for visibility - still struggling with this

Hey @rmol two quick questions:

  1. Are you sending your fine tuned model system instructions?
  2. Are you asking for responses in JSON format?
