[Bug]: Demo is not working

[matsk-sinch]

What happened?

On the Readme from https://github.com/google/A2A/tree/main/demo:

Running the examples > Step 4:
This path doesn't exist: cd ../../samples/agents/google_adk/

I tried to run with:
A2A/samples/python/agents/google_adk

And I got this error:
INFO: ::1:50143 - "POST / HTTP/1.1" 200 OK
ERROR:task_manager:An error occurred while streaming the response: Failed to parse the parameter date: str | None = None of function create_request_form for automatic function calling. Automatic function calling works best with simpler function signature schema,consider manually parse your function declaration for function create_request_form.

I am struggling with this too.

I added Options to the create_request_form method and modified the formula as follows.

def create_request_form(date: Optional[str] = None, amount: Optional[str] = None, purpose: Optional[str] = None) -> dict[str, Any]:

The error no longer occurs, but the UI only displays only the message "Request has been made to an agent" and the form is not displayed.
I need help.
