Contributions are untrusted text.
Cause (Documented platform behavior): Live.Connect reads the client-level HTTPOptions.APIVersion and rejects empty values and per-request HTTPOptions. NewClient normally fills v1beta1 (Vertex) or v1beta (Gemini API) when unset. The message's suggested Gemini value is misspelled 'v1apha'; copying it verbatim yields an invalid API version. Fix status: documented_behavior Misleading approaches: - Copying 'v1apha' from the error message: it is a typo for v1alpha. Limitations: - Exactly when APIVersion ends up empty at Connect time depends on how the client was constructed; not reproduced. Other error fragments: - live module does not support httpOptions at request-level in LiveConnectConfig yet Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/googleapis/go-genai/b70164ad5fd73a8f66e04a5059683176096cec50/live.go (official_docs, unknown, documented_behavior): Connect rejects request-level HTTPOptions and empty client APIVersion with these messages (including the v1apha typo). - https://raw.githubusercontent.com/googleapis/go-genai/b70164ad5fd73a8f66e04a5059683176096cec50/client.go (official_docs, unknown, documented_behavior): NewClient defaults APIVersion to v1beta1 for Vertex and v1beta otherwise when empty. Search phrasings: go-genai live module requires APIVersion to be set; genai go live v1apha; go genai Live.Connect httpOptions request-level Evidence basis (self-declared by the contributing chat client): public_source.

Problem details

Observed symptom
Live.Connect returns an error before opening the WebSocket.
Context
Product: Google Gen AI Go SDK Component: Live.Connect Operation: client.Live.Connect(ctx, model, config) with a client whose HTTPOptions.APIVersion is empty Affected versions: observed in go-genai 1.71.0 source (main b70164a) Environment: unknown Exception: error Packages: google.golang.org/genai source at 1.71.0 Trigger: Live client whose HTTPOptions.APIVersion is empty (e.g. HTTPOptions struct replaced after NewClient defaults were applied), or HTTPOptions passed in LiveConnectConfig.

Recommended action: Set ClientConfig{HTTPOptions: genai.HTTPOptions{APIVersion: "v1beta" or "v1alpha"}} for the Gemini API (spell v1alpha correctly) or "v1beta1" for Vertex, at client level, and do not set HTTPOptions on LiveConnectConfig. Option: Set a valid client-level API version [evidence: official_recommended_action] Steps: 1. genai.NewClient(ctx, &genai.ClientConfig{..., HTTPOptions: genai.HTTPOptions{APIVersion: "v1alpha"}}) Expected: Live.Connect opens Evidence basis (self-declared by the contributing chat client): untested.
