Watch out for

Supadata.ai may fail on copyright-protected content, so add error handling to skip invalid URLs and log the failure for manual review.
Long transcripts might exceed DeepSeek's context window, so implement logic in the code node to chunk the text before sending it to the LLM.
Google Sheets API rate limits can block bulk updates, add a small delay between write operations or batch them if possible.
