使用 Python fetch.fail_request 的 Selenium 4 chrome devtools 不会使请求失败，而是将其保持为待处理

Question

In the following sample code the fail_request is not failing the request but simply keeping it as pending. I have similar issues with get_response_body or fulfill_request.

However all requests that are let to continue (using continue_request) are without any issues.

The import for GeneralFunctions is used for a function that returns a driver object with predefined actions. The import for testSetup provides access to generally used variables.

Is there something that I am doing wrong or is this a Selenium issue when using it with Python?

• Python version: 3.10
• Selenium webdriver version: 4.3.0
• Webdriver-manager version: 3.8.0 (used to download the latest chrome driver).
• Trio version: 0.20.0
• Chrome version: 103

import trio
import time
from Setup.Setup import testSetup
from Setup.General import GeneralFunctions
from selenium.webdriver.common.by import By
generalFunctions = GeneralFunctions()
async def main1():
    driver = generalFunctions.newChrome(testSetup.url)
    time.sleep(6)
    async with driver.bidi_connection() as connection:        
        session, devtools = connection.session, connection.devtools
        await session.execute(devtools.fetch.enable())
        listener = session.listen(devtools.fetch.RequestPaused)
        async with trio.open_nursery() as nursery:
            driver.refresh()
            async for event in listener:
                if "userData" in str(event.request.url) and event.request.method == "GET":
                    try:
                         await session.execute(devtools.fetch.fail_request(event.request_id, '{"error_reason": "aaaa"}'))
                        
                    except:
                        print("problem with target request")
                else:
                    try:
                        await session.execute(devtools.fetch.continue_request(event.request_id))
                    except:
                        print("problem with regular request")


async def main2():
    await main1()


trio.run(main2)

我自己想出来了 - 我没有检查异常错误，问题是 fetch.fail_request 需要第二个参数是这样的：

await session.execute(devtools.fetch.fail_request(event.request_id, devtools.network.ErrorReason.FAILED))
