Description

In the section starting with

Let’s wrap the sql_db_query tool in a node that receives human input. We can implement this using the interrupt function. Below, we allow for input to approve the tool call, edit its arguments, or provide user feedback.

There is the code:

@tool(
    run_query_tool.name,
    description=run_query_tool.description,
    args_schema=run_query_tool.args_schema
)

and when I run, I get the error:

TypeError                                 Traceback (most recent call last)
Cell In[7], line 1
----> 1 @tool(
      2     run_query_tool.name,
      3     description=run_query_tool.description,
      4     args_schema=run_query_tool.args_schema

TypeError: 'StructuredTool' object is not callable

I am using python 3.14.5.

I have a pyproject.toml:

[project]
name="sql_agent"
version="0.1.0"
description="sql_agent"
requires-python=">=3.14.0"
dependencies = [
    "jupyterlab",
    "langchain",
    "langgraph",
    "langchain-openai",
    "langchain_community",
    "duckduckgo-search",
    "requests",
    "sympy"
]

and

$ uv pip list | grep langchain
langchain                 1.3.1
langchain-classic         1.0.7
langchain-community       0.4.2
langchain-core            1.4.0
langchain-openai          1.2.2
langchain-protocol        0.0.15
