Original Pull Request: https://github.com/langchain-ai/langgraph/pull/6410

State: closed
Merged: Yes

Hi all,
I found out that the sync and async code examples of the task function in libs/langgraph/langgraph/func/__init__.py have a typo:

    Example: Sync Task
        ```python
        from langgraph.func import entrypoint, task


        @task
        def add_one(a: int) -> int:
            return a + 1


        @entrypoint()
        def add_one(numbers: list[int]) -> list[int]:
            futures = [add_one(n) for n in numbers]
            results = [f.result() for f in futures]
            return results


        # Call the entrypoint
        add_one.invoke([1, 2, 3])  # Returns [2, 3, 4]
        ```

Both task and entrypoint functions have the same name which gives an error.

This is a small PR to fix this
