RuntimeError('Event loop is closed') on running the sample code on test paper

[Ghost---Shadow]

Here is the code

from connectedpapers import ConnectedPapersClient

DEEPFRUITS_PAPER_ID = "9397e7acd062245d37350f5c05faf56e9cfae0d6"

# TEST_TOKEN allows access ONLY to the paper with the id DEEPFRUITS_PAPER_ID
client = ConnectedPapersClient(access_token="TEST_TOKEN")
remaining_uses_count = client.get_remaining_usages_sync()
print(f"Remaining uses count: {remaining_uses_count}")
free_access_papers = client.get_free_access_papers_sync()
print(f"Free access papers: {free_access_papers}")
graph = client.get_graph_sync(DEEPFRUITS_PAPER_ID)
assert graph.graph_json.start_id == DEEPFRUITS_PAPER_ID

Here is my trace

Here is my python

Python 3.8.15 (default, Nov 24 2022, 14:38:14) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on win32

[Ghost---Shadow]

Using my early access token gives the same problem

[KanHarI]

Hi, I will find a windows anaconda setup to test on and try to reproduce. Does this error reproduces outside of Anaconda? Can you try maybe creating a venv, installing the PyPi package and testing there?

[Ghost---Shadow]

Changing the sync functions to this fixes it. Thanks GPT4

import nest_asyncio
...
class ConnectedPapersClient:
    ...
    def get_free_access_papers_sync(self) -> List[PaperID]:
        nest_asyncio.apply()
        return asyncio.run(self.get_free_access_papers_async())

[KanHarI]

Deploying a fix in a few minutes, thanks

[KanHarI]

Fixed in https://github.com/ConnectedPapers/connectedpapers-py/pull/3

[KanHarI]

Fix deployed. Please comment here if the issue persists for anyone with the latest version

[KanHarI]

(Assuming this is fixed, please open a new issue if anyone encounters this again)

[Ghost---Shadow]

I still see the old code after pip installing. Did it deploy correctly?
