When does this happen?

IF When using Google's Vertex AI grounding Tool with LangChain's create_react_agent, an AttributeError occurs because Google's Tool object lacks a 'name' attribute required by LangChain's BaseTool.

How others solved it

THEN Migrate from the deprecated create_react_agent to ChatVertexAI, which directly supports Google grounding tools. Replace agent creation with direct invocation of ChatVertexAI, passing the tool list to the model constructor.

from langchain_google_vertexai import ChatVertexAI
llm = ChatVertexAI(model='gemini-1.5-pro', tools=[tool])
response = llm.invoke(user_prompt)
