Structured Output is not working for Teams

[Anan7Codes]

Below is a sample code, a minimal/mock version of the agent I am trying to build. I can't seem the get the structured output the way I want however I look at it. The idea is to get a structured output by making it work as a team and then use that to render components on my frontend later, but right even if I use Gemini, Claude or Deepseek, the response is always a string with other random texts in b/w.

Explaining what I am trying to achieve here just in case there is a much better approach, would really appreciate it.

from agno.agent import Agent
from agno.team import Team
from agno.app.fastapi.app import FastAPIApp
from agno.app.fastapi.serve import serve_fastapi_app
from typing import List, Any
from pydantic import BaseModel, Field

# Minimal model import (replace with your preferred model)
from agno.models.google import Gemini

# Pydantic classes remain unchanged
class AnalyticsResult(BaseModel):
    title: str = Field(..., description="Title of the analytics result, e.g., 'Average Monthly Sales'")
    data: List[Any] = Field(..., description="Data for the result, suitable for chart rendering")
    type: str = Field(..., description="Recommended visualization type: 'card', 'bar_chart', 'line_chart', etc.")

class AnalyticsResponse(BaseModel):
    results: List[AnalyticsResult] = Field(..., description="List of analytics results")

# Minimal model instance
gemini_model = Gemini(id="gemini-2.5-flash-preview-05-20", temperature=0.2)

# Agent 1: Simple Q&A agent
qa_agent = Agent(
    name="QnA Agent",
    model=gemini_model,
    instructions="""
        You are a helpful assistant. Answer user questions as simply and clearly as possible. If you don't know the answer, say so.
        Always return your answer in the AnalyticsResponse format.
    """,
)

# Agent 2: Fun explainer
fun_explainer = Agent(
    name="Fun Explainer",
    model=gemini_model,
    instructions="""
        You are a playful explainer. Take the answer from the QnA Agent and rephrase it in a fun, friendly way. Do not add new information.
        Only explain what you receive, and always use simple language.
    """,
)

# Minimal team setup
simple_team = Team(
    name="Simple QnA Team",
    mode="collaborate",
    members=[qa_agent, fun_explainer],
    model=gemini_model,
    instructions=[
        "The QnA Agent answers the question directly.",
        "The Fun Explainer rephrases the answer in a friendly way.",
        "Do not mention teams or agents in your response.",
    ],
    response_model=AnalyticsResponse,
)

# FastAPI app
app = FastAPIApp(team=simple_team).get_app()

if __name__ == "__main__":
    serve_fastapi_app("main:app", port=8001, reload=True)
