Celery how to pass arguments to linked task (which is bound)?

I have 2 tasks, which one after success should start second and pass results. Both task are bind=True because of logic of reporting retries.

I call this task by:

async def foobar(x: int):
    task = foo.apply_async(kwargs={'x': x}, link=bar.si())

But have no idea how to pass result to bar task. Docs show only example without bind, and in my case result is not passed to second task bar

Traceback show that y is not passed:

Traceback (most recent call last):
