`parameters_json_schema` seems not supported by Gemini Live API

[longcw]

When using parameters_json_schema in types.FunctionDeclaration, it works for the regular gemini LLM model like gemini-2.0-flash-001, but not work for the live api model gemini-2.0-flash-live-001 or gemini-2.5-flash-preview-native-audio-dialog.

It model can call the function but with an empty argument. It works when using parameters of types.FunctionDeclaration. Does the Gemini Live API supports parameters_json_schema?

FYI, I am using google-genai 1.26.0.

Hey @longcw
Thank you for reaching out!
I was able to use parameters_json_schema with live api models . Please find the gist.
Thank you!

@janasangeetha thanks for the reply! If you print the chunk.tool_call in the live model example, the argument is empty from the tool call, this is exactly the issue I encountered

function_calls=[FunctionCall(
  args={},
  id='function-call-60813826532501183',
  name='get_current_weather'
)]
