The current `create_agent` agent's `invoke()` response cannot include a `structured_response`.

• This is a bug, not a usage question.
• I added a clear and descriptive title that summarizes this issue.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).
• This is not related to the langchain-community package.
• I read what a minimal reproducible example is (https://stackoverflow.com/help/minimal-reproducible-example).
• I posted a self-contained, minimal, reproducible example. A maintainer can copy it and run it AS IS.

Example Code

Such as

class StructuredResponse(BaseModel):
    id: str
    context: str

agent = create_agent(model=llm, response_format=StructuredResponse)

result = agent.invoke()

Error Message and Stack Trace (if applicable)

The standard result must include both "message" and "structured_response"; however, currently, it only contains "message."

Description

I have printed the response content; it is also in JSON format, but it only includes the "message." The final AIMessage contains the complete structured result. The "finish_reason" being "stop" indicates that it worked correctly.
