Steps to reproduce

replace ChatOpenAi with this in graph.tsx file : `import { ChatGoogleGenerativeAI } from "@langchain/google-genai";

// rest of the code

const llm = new ChatGoogleGenerativeAI({ temperature: 0, model: "gemini-1.5-flash-latest", streaming: true, apiVersion: "v1beta", }).bindTools(tools);`

@bracesproul please help me resolving this

@his-maj-esty You can't only replace ChatOpenAI with ChatGoogleGenerativeAI. Gemini takes different inputs than Open AI API. You'll need to read the Gemini docs to figure out the syntax to send to the Gemini API. Probably start here: https://ai.google.dev/gemini-api/docs/api-overview

@dylanmclane I think langchain handles that under the hood, by providing a unified api for all the providers

that's what I thought

I tried using import { ChatGoogle } from "@langchain/google-webauth"; with the configuration apiVersion: "v1beta", and I had the same error.

You can you ChatVertexAI instead of ChatGoogleGenerativeAI ,It works this way but the process of setting up vertex AI is a bit lengthy. But be carefull there won't be any tool calling in the result.tool_calls array. You will need to manually get the tools from the results.additional_kwargs.tool_calls
