Watch out for

Bright Data may return incomplete data if Facebook changes its anti-bot measures, so implement a retry mechanism with logging.
Google Sheets has row limits and API quotas that can cause failures during bulk updates, so add error handling for rate limits.
LLMs can hallucinate sentiment for posts with heavy slang or emojis, so include examples of ambiguous cases in the system prompt.
Facebook group privacy settings may block scraping if the user is not a member, so verify access permissions before running the scraper.
