Solutions

1. Check that the custom Gemini API host is correct and reachable.
2. Verify the API key passed in the /models?key= query is valid and has Generative Language API access.
3. Inspect the stringified response body for the upstream error (e.g. API_KEY_INVALID).
4. Confirm the endpoint returns the standard Gemini list-models shape with a 'models' array.

Example fix

const json: Response = await res.json()
if (!json.models) {
  console.error('Custom Gemini listModels error:', json)
}
