Reasoning model with structured output

### Checked other resources - [x] This is a bug, not a usage question. For questions, please use the LangChain Forum (https://forum.langchain.com/). - [x] I added a clear and detailed title that summarizes the issue. - [x] I read what a minimal reproducible example is (https://stackoverflow.com/help/minimal-reproducible-example). - [x] I included a self-contained, minimal example that demonstrates the issue INCLUDING all the relevant imports. The code run AS IS to reproduce the issue. ### Example Code ```python def get_ChatOpenAI( model=settings.MODEL_NAME, base_url=settings.BASE_URL, api_key=settings.API_KEY ): llm = BaseChatOpenAI( model=model, base_url=base_url, api_key=api_key, ) return llm class Section(BaseModel): name: dict = Field( description="Name of the analyzed corporate strategic focus e.g.: {'战略点名称': '智能流程自动化'}" ) information: dict = Field( description="description of the analyzed corporate strategic focus e.g.: {'战略点说明': '在金融或医疗领域，通过大数据风控模'}" ) class AnalysisResult(BaseModel): result: List[Section] = Field( description="All of Name and description and all plan of the analyzed corporate strategic focus" ) analysis_chain = system_prompt | get_ChatOpenAI().with_structured_output(AnalysisResult) result = analysis_chain.invoke() ``` ### Error Message and Stack Trace (if applicable) ```shell File "E:\大模型\PyCharm 2023.1.2\plugins\python\helpers\pydev\pydevd.py", line 1496, in _exec pydev_imports.execfile(file, globals, locals) # execute the script ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "E:\大模型\PyCharm 2023.1.2\plugins\python\helpers\pydev\_pydev_imps\_pydev_execfile.py", line 18, in execfile exec(compile(contents+"\n", file, 'exec'), glob, loc) File "E:\strategy_analysis\analysis_graph\analysis_node.py", line 267, in <module> result = asyncio.run(graph.ainvoke( ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\ProgramD…
