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.
