To resolve the "unclosed event loop" error when running Langflow version 1.0.19.post2 on Mac with Python 3.10, you should set the environment variable OBJC_DISABLE_INITIALIZE_FORK_SAFETY to YES. This is necessary to avoid errors when running gunicorn on MacOS. You can do this by adding the following code to your script or setting it in your environment before running the application:

import os
os.environ["OBJC_DISABLE_INITIALIZE_FORK_SAFETY"] = "YES"

Additionally, set the no_proxy environment variable to * to avoid errors with gunicorn:

os.environ["no_proxy"] = "*"

These settings are specifically mentioned in the set_var_for_macos_issue function in the Langflow code, which is designed to address this issue on MacOS ^[1][2].

hey @kkjinping @SavvySupport

Hi! Thanks for reporting this. We've recently released Langflow v1.1. Could you please:

1. Update Langflow using:

   pip install langflow -U

2. Try running it again with:

   langflow run

Let me know if the error persists. If it does, please share the error message so I can help further.
