Also use a patched version of langchain-google-vertexai module to address an issue with LangGraph with ChatVertexAI.
This is required to use tool calling feature.
…xAI. ChatVertexAI responds with an AIMessage instead of a plain JSON-formatted string. The string content is in the "content" key of the AIMessage object returned. The issue occurred because now ChatVertexAI responds with a plain string (not a JSON formatted string) when directly responding to a user's query. However, while trying to invoke a tool, it does not provide the corresponding values in "tool_calls" key, but instead returns a JSON-formatted string with tool name and arguments. In this case, the "content" field's string needs to be parsed like before.
