[Bug]: Type error in Utils.py #1106
Description
Do you need to file an issue?
- I have searched the existing issues and this bug is not already filed.
- I believe this is a legitimate bug, not just a question or feature request.
Describe the bug
LightRAG is not finishing cleanly. Producing a Type error. See error below:
Exception ignored in: <function LightRAG.del at 0x000001BE034E6FC0>
Traceback (most recent call last):
File "c:\Users\lkden\OneDrive\Documents\GitHub\pythonLearning\lightrag2-env\Lib\site-packages\lightrag\lightrag.py", line 433, in del
File "c:\Users\lkden\OneDrive\Documents\GitHub\pythonLearning\lightrag2-env\Lib\site-packages\lightrag\lightrag.py", line 438, in _run_async_safely
File "c:\Users\lkden\OneDrive\Documents\GitHub\pythonLearning\lightrag2-env\Lib\site-packages\lightrag\utils.py", line 863, in always_get_an_event_loop
TypeError: 'NoneType' object is not callable
Steps to reproduce
Using Python 3.12.6
LightRAG 1.2.5
Run the demo code in the Readme.txt file. When everything is done and the Python script is finishing, then the error is shown. This is also happening when using setting up LightRAG to be "served" in a Python web server.
Expected Behavior
Close and finish cleanly and quietly.
