Hey, the screenshots aren’t loading for me so I can’t see the error — could you paste the actual error message as text and let us know what n8n version you’re running? Also worth mentioning which specific node you’re using (Google Gemini Chat Model, PaLM, etc) and whether the API key works fine when you test it outside of n8n.
Hi @chunwen0907 Welcome!
There is no particular problem with AZURE, but i would say should try revoking your credentials, as your ERROR says that the service is receiving too many requests from you. Let me know if that works. {ALSO CONSIDER USING Google’s AI STUDIO for better AI Support , I personally use that and it works all the time}
