Description
When I use the add_request_handler to try to add or modify headers from a request, the headers object is always None, and even if I add some header to it, it doesn't seem to affect the request or be actually added to it.
On selenium/webdriver/common/bidi/network.py, we seem to be missing the line (block starting at 131)
headers=event_data.params["request"].get("headers", None)
Reproducible Code
import time
from selenium import webdriver
# BiDi-capable Chrome setup
options = webdriver.ChromeOptions()
options.enable_bidi = True
driver = webdriver.Chrome(options=options)
# Define a basic callback that logs headers
def log_google_requests(request):
if "google" in request.url:
print(f"Intercepted URL: {request.url}")
print("Headers:", request.headers)
request.continue_request()
# Attach network handler
driver.network.add_request_handler(
event="before_request",
callback=log_google_requests
)
# Trigger a request to Google
driver.get("https://www.google.com")
time.sleep(5)
driver.quit()Debugging Logs
