You can set APIVersion to v1beta1 for BackendVertexAI or v1apha for BackendGeminiAPI' (note typo 'v1apha') ## Body 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.
