Troubleshooting

Video stuck in “processing”? → Increase the Wait node duration (30–60 sec).

Voice note too robotic? → Switch to a premium ElevenLabs voice.

Research not specific enough? → Strengthen the system prompt with more constraints.

Emails not arriving? → Ensure Gmail OAuth has send permission configured.

API authentication errors? → Check credentials in each node (OpenAI, Perplexity, HeyGen, etc.).
