Code generation is still broken

Google AI Studio
1 
generation_config = {
  "temperature": 0,
  "top_p": 0.95,
  "top_k": 64,
  "max_output_tokens": 8192,
  "response_schema": content.Schema(
    type = content.Type.OBJECT,
    enum = "[]",
    required = "["entities"]",

A clear example where the field required is not proper Python.

Is there a bug tracker on this ?
