error occurring while using Gemini with multiple tools

[mstrYoda]

When I run Gemini model with multiple tools (FileTools and ShellTools), it gives the following error. I found that the issue was related with Gemini on older modals but it seems like they fixed it on model version 2. But still I got the error.

GoogleCloudPlatform/generative-ai#636 (comment)

Here is my example code:

gemini_model = Gemini(id="gemini-2.0-flash", api_key=api_key)

team = Agent(
    model=gemini_model,
    role="Software Engineer",
    tools=[FileTools(), ShellTools()],
    add_history_to_messages=True,
    num_history_responses=10,
    show_tool_calls=True,
    monitoring=True,
    debug_mode=True,
    stream=False,
)

Hi @mstrYoda Would pease mind sharing all of the code you are running + prompts so we can try to reproduce your error?
