    Missing elements are a frequent issue, especially if the website layout changes. I update my selectors regularly and use error logging to catch these early.

    Encountering CAPTCHAs mid-scrape can stop the script. I’ve found that using services like 2Captcha or rotating proxies helps minimize this.

    HTTP 403 or 404 errors often mean the server is blocking requests. Changing user agents or adding headers to mimic a real browser can sometimes solve this.

    Slow response times or timeouts happen on heavily trafficked sites. I usually add a retry mechanism with exponential backoff to handle this.

    Unexpected JavaScript changes can break scrapers. Tools like Playwright or Puppeteer, which handle dynamic content better, have been lifesavers here.

    IP bans can crop up if the server detects unusual traffic. Using residential proxies or rotating through IPs can reduce the risk.

    Parsing errors, like trying to pull from a non-existent element, can be fixed by adding conditional checks or using try-except blocks.

    If none of these work, I sometimes resort to scraping at off-peak hours. Sites often relax restrictions when there’s less user activity.
