Watch out for

YouTube API requests can hit rate limits quickly, so implement a delay node between batch updates to stay within quota.
Gemini responses may include markdown formatting like backticks which will break YouTube's metadata fields, so add a code node to strip non-text characters.
The workflow might fail silently if the video ID is invalid or the account lacks permissions, so add error handling nodes that log specific API error codes to Sheets.
Translating long descriptions can exceed token limits or cause truncation, so split the description into chunks before sending them to the LLM for processing.
