Langgraph agent

[ravneetgrewal]

I am running the langgraph agent sample (Currency Agent).
I am sending this request:

curl -X POST http://localhost:10000   -H "Content-Type: application/json"   -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tasks/send",
    "params": {
      "id": "task123",
      "sessionId": "session456",
      "acceptedOutputModes": ["text"],
      "message": {
        "role": "user",
        "parts": [
          {
            "type": "text",
            "text": "How much is 1 USD to EUR?"
          }
        ]
      }
    }
  }'

the server is printing this on the terminal:
INFO: ::1:61795 - "POST / HTTP/1.1" 200 OK INFO:common.server.task_manager:Upserting task task123 INFO:agents.langgraph.task_manager:No push notification info found for task task123 INFO:agents.langgraph.task_manager:No push notification info found for task task123

what am I missing in the request, I was hoping this is a simple sync request, not a callback/notification.
