Error 1007 "Invalid argument" with Gemini Live API (bidiGenerateContent) - Need beta access

Gemini API
1

Hi Google team,

I’m building a production AI voice ordering system for restaurants using Twilio Media Streams + Gemini Live API, but I’m hitting a blocker.

Issue:
Getting error 1007 “Request contains an invalid argument” when connecting to the Live API WebSocket endpoint.

Setup:

  • Model: gemini-2.0-flash-exp
  • Endpoint: wss://generativelanguage.googleapis.com/ws/google.ai.generativelanguage.v1alpha.GenerativeService.BidiGenerateContent
  • Billing: :white_check_mark: Enabled with $300 credits
  • Generative Language API: :white_check_mark: Enabled
  • Current quota: Only 2 RPM (too low for production)

Error logs:
The connection establishes successfully, but immediately closes with error 1007 after sending the setup message.

Questions:

  1. Does my account need beta access to use the Live API?
  2. Can you increase my quota for gemini-2.0-flash-exp to at least 60 RPM?
  3. Is this model ready for production, or should I wait for a stable release?

Why Gemini:
This is a cost-effective solution for small restaurants. Gemini’s pricing (~$0.02/min) is essential for our business model, as alternatives like OpenAI ($0.30/min) are too expensive.

Any help would be greatly appreciated! Thank you!
