TCBGeminiBot extension always returns Error 429 (Too Many Requests) even on first request

Hello everyone,

I am requesting help regarding the TCBGeminiBot.aix extension for using Google Gemini in MIT App Inventor.

I have built a simple chatbot app using this extension, but it has never worked even once. From the very first request, it always returns:

Error 429 – Too Many Requests

I am confident that this issue is not related to request limits, and below is a detailed description of what I have tested.

What I have confirmed

  • The Gemini API key is valid

  • The key was created in Google AI Studio (aistudio.google.com), not in Google Cloud Console

  • The key works correctly in Google AI Studio Playground (simple prompts return responses normally)

  • The API key is:

    • Unrestricted
    • Newly created
    • Used with zero prior requests

  • The error occurs immediately on the first request, every time

  • Waiting time after key creation (30+ minutes) did not change the result

Thank you in advance to anyone who can share his thoughts or insights.
