Fix ToolInvocationError

✅ Solution

ToolInvocationError in LangGraph usually arises from unhandled exceptions within a tool's execution or from Pydantic validation failures when passing arguments to tools, especially those with `ToolRuntime` parameters. To fix it, ensure your tool functions have robust error handling (try-except blocks) and meticulously validate the data passed to the tool using Pydantic schemas matching the expected input types, paying special attention to runtime dependencies. This ensures the tool executes properly and returns data in the expected format.
