[Bug]: Fast API and a2a-python integration issue

[baaron42]

What happened?

Hi,

I noticed that when I create a skill such as:

class SomeAgent(A2AServer):

    @skill(name="someskill", description="Some skill")
    def dosomething(self, task: str = None):
          return {"successful":True,"message":"Generating trivia"}

Then add the a new router to the app:

router = APIRouter()
agent_instance.setup_routes(router)
app.include_router(router, prefix="/a2a/trivia")

That the signatures of the method do not match for the methods such as tasks_send in a2a_server.py.

As a result, I am forced to override the signatures such that all methods now have the expected parameter that Fast API sends.

async def tasks_send(request: Request):

I am using the following versions:

fastapi==0.116.1
python-a2a==0.5.10

Thank you,
Aaron
