Watch out for

Decodo may fail if the website structure changes, so add error handling to retry or log failures gracefully.
Gemini API calls can be slow and costly, so batch process reviews instead of calling it per individual comment.
Telegram alerts might duplicate if the workflow runs multiple times on the same data, so track processed review IDs in Sheets.
HTML selectors often break due to dynamic content loading, so verify the scraped data contains actual text before sending to LLM.
