Python 如何查找此web抓取（bot）代码中的错误？

我正在尝试构建一个机器人来发送linkedin中的请求。但运行此代码后，它一直工作到42行，然后停止。我怎样才能找出错误呢？有一个包含用户和密码的config.txt文件。为了安全起见，我不提供此文件。在这方面有人能帮我吗

import os, random, sys, time
from selenium import webdriver
from bs4 import BeautifulSoup

browser = webdriver.Chrome('C:\Program Files (x86)\chromedriver.exe')
browser.get('https://www.linkedin.com/uas/login?trk=hb_signin')

file = open('config.txt')
lines = file.readlines()
username = lines[0]
passwd = lines[1]

elementID = browser.find_element_by_id('username')
elementID.send_keys(username)

elementID = browser.find_element_by_id('password')
elementID.send_keys(passwd)

elementID.submit()

myID = '/in/kafee-khan-097a5b129/'
fulllink = 'https://www.linkedin.com/' + myID
browser.get(fulllink)

visitedProfiles = []
profileQueued = []

def getNewProfileIDs(soup,profileQueued):
    profilesID = []
    pav = soup.find('div',{'class':'pv-browsemap-section'})
    all_links = pav.findAll('a',{'class':'pv-browsemap-section__member ember-view'})
    for link in all_links:
        userID = link.get('href')
        if((userID not in visitedProfiles) and (userID not in profileQueued)):
            profilesID.append(userID)
    return profilesID
    

soup = BeautifulSoup(browser.page_source, "html.parser")
getNewProfileIDs(soup, profileQueued) 

while profileQueued:
    try:
        visitedID = profileQueued.pop()
        visitedProfiles.append(visitedID)
        fullLink = "hhttps://www.linkedin.com" + visitedID
        browser.get(fullLink)

        browser.find_element_by_class_name('pv-s-profile-actions pv-s-profile-actions--connect ml2 artdeco-button artdeco-button--2 artdeco-button--primary ember-view').click()

        browser.find_element_by_class_name('mr1').click()

        message = "Hello, I am Muktadir. I like to connect with you."
        elementID = browser.find_element_by_id('custom-message')
        elementID.send_keys(message)

        browser.find_element_by_class_name('artdeco-modal__dismiss').click()

        soup = BeautifulSoup(browser.page_source, "html.parser")
        try:
            profileQueued.extend(getNewProfileIDs(soup, profileQueued))
        except:
            print('Continue')

    except:
        print('error')

调试

在软件开发实践中，您可以发现代码发生了什么。 如果您使用的是vs代码

Vs代码是一个很好的代码编辑器，有很多插件可以将其转换为

但还有其他选项，如“我还想知道如何调试此代码”。请仅针对每个SO问题提出一个问题
