CDP handlers not working on Debian Linux

[carnerero]

Hi!

I started using SeleniumBase on my Windows 10 without problems, after some digging about alternatives of the use of selenium-wire. I found the example of the network traffic handlers and adapted it to my project. It worked fine. But my surprise came latter, when I tried it of a Debian system. It did work, and after several combinations of parameters I didn't found the correct combination if it exists.

	display = pyvirtualdisplay.Display(visible=False, size=(device.width, device.height))
	display.start()
	
	with SB(disable_csp=True, headless2=True, uc=True) as bc:
		
		responses = {}
		async def response_handler(event: ResponseReceived) -> None:
			response = event.response
			if response.headers.get("Content-Type", "").startswith("text/html"):
				print(f'{response.url} -> {response.status}')
				responses[response.url] = response.status

		bc.activate_cdp_mode(target_url)
		bc.cdp.add_handler(ResponeReceived, response_handler)
		bc.set_default_timeout(30)

That is the version I was using in the Linux system. Am I missing something? It loaded the "target_url" and I was able to take screenshots, but it didn't registry any activity. I tried also to handle requests. Any help would be welcome!

I have examples running in GitHub Actions that display responses and XHR:

• https://github.com/mdmintz/undetected-testing/actions/runs/15712660283/job/44274499313

I have other examples here where CF Turnstiles are clicked:

• https://github.com/mdmintz/undetected-testing/actions/runs/15704681679/job/44247602812

Note that those examples use Ubuntu... not Debian.
Ubuntu is the only officially supported Linux system for UC Mode / CDP Mode.
If using other Linux systems such as Debian for UC Mode / CDP Mode, then you're on your own.

Thank you! Sorry for the trouble.

Good morning! I took raw_res_sb.py and tested it on the Debian machine, it worked partially. That is, I saw the requests but the response handler didn't print anything. That's exactly the part I'm most interested in to get the http_status. Any suggestions?

P.S.: Thanks for the quick response xD
