Problems with har on osx

[Virgula0]

I'm trying to use proxy.newHar in python but this throws an exception:

from browsermobproxy import Server
dict={'port':7070}
server = Server(path="./browsermob-proxy-2.1.4/bin/browsermob-proxy",options=dict)
server.start()
proxy = server.create_proxy()

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

profile  = webdriver.ChromeOptions()
profile.add_argument('--proxy-server=%s' % (proxy.proxy))
profile.add_argument('--ignore-ssl-errors=yes')
profile.add_argument('--ignore-certificate-errors')
driver = webdriver.Chrome(ChromeDriverManager().install(),chrome_options=profile)
proxy.new_har("google")
driver.get("http://www.google.co.uk")
proxy.har # returns a HAR JSON blob

server.stop()

but I get:

Traceback (most recent call last):
