claude-code - 💡(How to fix) Fix [Bug] Missing pythoncom.CoInitialize() in Flask request threads for COM initialization [1 participants]

TL;DR

The issue can be fixed by calling pythoncom.CoInitialize() in the _get_app function of wps_com/insert_image.py to initialize COM for each Flask request thread.

Guidance

• The root cause is the missing call to pythoncom.CoInitialize() in the _get_app function, which is necessary for COM initialization in a multi-threaded Flask environment.
• To verify the fix, check the server logs for the presence of the one_col anchor=... output after updating the _get_app function.
• Update the wps_com/insert_image.py file by adding the necessary import statement and calling pythoncom.CoInitialize() in the _get_app function.
• Ensure that the pythoncom module is properly imported and initialized before using COM-related functions.

Example

import pythoncom
def _get_app(visible: bool = False):
    try:
        import win32com.client as wc
        pythoncom.CoInitialize()  # Initialize COM
        # ...
    except ImportError:
        # ...

Notes

The provided solution assumes that the pythoncom module is available and properly configured in the environment. If issues persist, further investigation into the COM initialization and threading may be necessary.

Recommendation

Apply the workaround by updating the _get_app function to include the call to pythoncom.CoInitialize(), as this directly addresses the identified root cause of the issue.
