Actual behaviour

The new headers response does not contain Dencun fields.

Steps to reproduce the behaviour

Run this Python script.

import asyncio
import websockets
import json

async def subscribe_new_heads():
    uri = "ws://{WS_ENDPOINT}"
    async with websockets.connect(uri) as websocket:
        subscription_request = {
            "jsonrpc": "2.0",
            "method": "eth_subscribe",
            "params": ["newHeads"],
            "id": 1
        }

        await websocket.send(json.dumps(subscription_request))

        while True:
            message = await websocket.recv()
            print(message)

asyncio.get_event_loop().run_until_complete(subscribe_new_heads())
