Google Gemini Grounding Tool: `'Tool' object has no attribute 'name'`

Checked other resources

• [X] I added a very descriptive title to this issue.
• [X] I searched the LangChain documentation with the integrated search.
• [X] I used the GitHub search to find a similar question and didn't find it.
• [X] I am sure that this is a bug in LangChain rather than my code.
• [x] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

from vertexai.generative_models import Tool, grounding
from langchain.agents import AgentExecutor, create_react_agent

tool = Tool.from_google_search_retrieval(grounding.GoogleSearchRetrieval())

try:
    agent = create_react_agent(llm=llm, tools=[tool], prompt=prompt_template)
except Exception as error:
    logger.exception(f"Error creating agent: {error}")
    raise error

Description

Using this as an example, I'm attempting to use gemini's grounding tool.

I expect my call to gemini to succeed. Instead, I get 'Tool' object has no attribute 'name'.

Looks like LangChain's BaseTool class expects a name attribute that google's Tool class doesn't implement, making them incompatible.

I'm going to leave this issue open but I was able to get around this by ripping out the (now deprecated) create_react_agent and using ChatVertexAI.

Hi, @BwL1289. I'm Dosu, and I'm helping the LangChain team manage their backlog. I'm marking this issue as stale.
