Hello Google Gemini API team,

We are investigating a persistent Gemini Live API failure affecting three AI speaking applications for Keiser University International Language Institute.

Observed behavior

- Each application fails before receiving setupComplete.
- The WebSocket closes with code 1006.
- The surfaced error is: “Request contains an invalid argument.”
- On October 16, 2026, the Google Cloud API metrics view filtered to six hours showed:
  - v1alpha.BidiGenerateContent: 38 requests; 44.74% errors
  - v1beta.BidiGenerateContent: 34 requests; 32.35% errors
  - Activity also included HTTP 200 and 409 responses.

Environment

- Shared Google Cloud project: AI Speaking Apps
- Project ID: gen-lang-client-07494010..
- Tier: Free Tier
- Generative Language API is enabled.

Troubleshooting already completed

- Used the documented minimal Live API setup.
- Tried an alternate model.
- Tried a newer SDK.
- The failure persists across all three applications.

We are reporting observations rather than asserting a root cause. Could Google please provide a project-specific diagnosis for why BidiGenerateContent/Live sessions are failing before setupComplete, including whether there is an eligibility, configuration, service-side, or other project-level condition we should address?

We can provide non-sensitive request identifiers or additional diagnostics privately if needed. We will not post API keys, credentials, or student data.

Thank you.
