Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• 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).

Example Code

OpenAIAssistantFinish(
                return_values={
                    "output": answer,
                    "thread_id": run.thread_id,
                    "run_id": run.id,
                },
                log="",
                run_id=run.id,
                thread_id=run.thread_id,
            ) 

this only return following fields, it should return usage details as well

Error Message and Stack Trace (if applicable)
