AttributeError: 'NoneType' object has no attribute 'update' when using Agno with Gemini model

General

Hi everyone,

I’m encountering an issue when trying to use Agno with the Gemini model and wanted to see if anyone else has experienced this or has any suggestions.

Problem:

I’m getting the following error:

AttributeError: 'NoneType' object has no attribute 'update'

This error occurs when I try to initialize and run an agent with the Gemini model.

Code:

Here’s the code I’m using:

from agno.agent import Agent, RunResponse  # noqa
from agno.models.google import Gemini

agent = Agent(model=Gemini(id="gemini-2.0-flash-001"), markdown=True)

# Get the response in a variable
# run: RunResponse = agent.run("Share a 2 sentence horror story")
# print(run.content)

# Print the response in the terminal
agent.print_response("Share a 2 sentence horror story")

Traceback:

The traceback points to the _get_request_kwargs method within the agno.models.google.Gemini class:

Investigation:

I’ve verified that the Gemini API is accessible and functioning correctly. I successfully made a direct request to the API using a PowerShell script, confirming that my API key and network connection are working. This suggests the issue lies specifically within Agno’s Gemini integration.

What I’ve Tried:

  • Restarted Kernel
  • Reinstalled agno

Environment:

  • agno version: “agno>=1.1.4”
  • google-genai version: “google-genai>=1.2.0”
  • Python version: 3.13.2 (initially), also tested with 3.12.9
  • Operating System: Windows

Question:

Has anyone else run into this issue? Any suggestions on how to resolve it would be greatly appreciated! It seems the config variable in agno.models.google.Gemini._get_request_kwargs is sometimes None when it should be a dictionary-like object.

Thanks in advance for any help!

fixed when agno==1.1.3 is working for Gemini model rather than using 1.1.4 version
