Watch out for

WhatsApp template approval can delay deployment so design message structures early and get them approved before launch.
Vector search relevance may drop with noisy sales jargon so implement text preprocessing to clean up the knowledge base entries.
Airtable API rate limits can cause data sync failures so add retry logic with exponential backoff in your n8n workflows.
Context window overflow occurs during long voice transcriptions so truncate history or summarize previous turns before sending to the LLM.
