Async discoveryengine_v1 client not working

[francescov1]

Determine this is the right repository

• I determined this is the correct repository in which to report this bug.

Summary of the issue

Context
I am trying to use the DocumentServiceAsyncClient but am getting event loop errors. I believe the library is creating separate event loops.

Expected Behavior:
I can use the async client without it creating event loops.

Actual Behavior:
When I call document_client.import_documents(), i get

RuntimeError: Task <Task pending name='Task-3' coro=<_wrap_awaitable() running at /Users/francescovirga/.pyenv/versions/3.11.7/lib/python3.11/asyncio/tasks.py:694> cb=[_release_waiter(<Future pendi...ask_wakeup()]>)() at /Users/francescovirga/.pyenv/versions/3.11.7/lib/python3.11/asyncio/tasks.py:431]> got Future <Task pending name='Task-2' coro=<UnaryUnaryCall._invoke() running at /Users/francescovirga/.local/share/virtualenvs/lighthouse-ai-chat-JRzDFnJw/lib/python3.11/site-packages/grpc/aio/_call.py:577>> attached to a different loop
