📄 Description

Overview

Added a warning and best-practice example to the ChatGoogleGenerativeAI documentation regarding the use of with_structured_output. This addresses a common issue where passing additional tools (like Google Search) directly into a structured output call causes the model to return a tool call instead of the expected schema, resulting in an AttributeError: 'NoneType' object has no attribute

Type of change

Type: Update existing documentation
