[BUG] LangChain design conflict: StructuredTool._run() missing 1 required keyword-only argument: 'config'

[brycecf]

Description
Continuation of #924, which was closed without providing a long-term solution.

With langchain-core==0.2.16, a new required arg was added to StructuredTool._run() as shown here. This breaks existing implementations using crewai_tools.BaseTool.

Steps to Reproduce
Create a custom tool using BaseTool.

Expected behavior
Elaborated on in #924, but this works with previous versions of langchain-core.

Screenshots/Code snippets
If applicable, add screenshots or code snippets to help explain your problem.

Environment Details:

• Operating System: Sonoma 14.5
• Python Version: 3.11.9
• crewAI Version: 0.35.5
• crewAI Tools Version: 0.4.26

Logs

Thought: <LLM output>
Action: custom_crew
Action Input: {"query": "<LLM-derived query>"}


I encountered an error while trying to use the tool. This was the error: StructuredTool._run() missing 1 required keyword-only argument: 'config'.

Possible Solution
None

Additional Context
langchain==0.2.12
langchain-core==0.2.28

I think we fixed this on crewAI side right @gvieira , can you give us more context on what versions you are using just to be sure :)

[gvieira]

That's correct. We did fix it a while a go. A version update will make it right.
