Nodriver uc.cdp.network.get_response_body() always returns None.

[xiahan4956]

my purpose is to use Nodriver to get the response content .
But .cdp.network.get_response_body() always returns None.
This is my code.
I think my issue is similar as
#1788
#1930

import asyncio
import datetime
import time
import pandas as pd
import os
import sys
from tqdm import tqdm
import nodriver as uc

sys.path.append(os.getcwd())
from utils import run_no_driver


request_ids = []
async def response_meta_handler(event):
    # if 'https://api.follow.is/entries' in event.response.url:
    request_id = event.request_id
    request_ids.append(request_id) 
    print("add request_id", request_id)
    with open("data/nodriver.txt", "a") as f:
        f.write(str(event)+"\n")


async def run():       

    url =  "http://www.google.com/"
    driver = await run_no_driver()
    tab =  await driver.get("about:blank")
    
    tab.add_handler(uc.cdp.network.ResponseReceived, response_meta_handler)
    await tab.send(uc.cdp.target.set_auto_attach(True, True))
    tab =  await tab.get(url)
    await asyncio.sleep(10)

    for request_id in request_ids:
        print(request_id)
        a = await asyncio.wait_for(tab.send(uc.cdp.network.get_response_body(request_id)), timeout=10)
        b = await asyncio.wait_for(tab.send(uc.cdp.fetch.get_response_body(request_id)), timeout=10)
        
        print(a)
        print(b)
    
    print(123)
    print(123)
    print(123)
  
    
if __name__ == "__main__":
    asyncio.run(run())

In this code . I can get reuqest_id
like

add request_id 32460.14
add request_id 32460.15
add request_id 32460.11
add request_id 32460.19
add request_id 32460.20
add request_id 32460.18
add request_id 32460.17
add request_id 32460.10

But when I use uc.cdp.network.get_response_body(request_id) or uc.cdp.fetch.get_response_body(request_id)
I always get None like

32460.40
None
None
