CumulusCI 4 refresh token error

[yippie]

Describe the bug

Since upgrading to CummulusCI 4, all commands that work with orgs are outputting the following error:

Exception ignored in: <_io.TextIOWrapper encoding='utf-8'> Traceback (most recent call last): File "/Users/kai.amundsen/.local/pipx/venvs/cumulusci/lib/python3.13/site-packages/cumulusci/core/config/sfdx_org_config.py", line 212, in refresh_oauth_token self.sfdx_info AttributeError: 'Capture' object has no attribute 'flush'

Reproduction steps

1. Upgrade to CumulusCI 4.0.1 and sf cli 2.67.7
2. run cci org browser --org <existing org alias>

Org will open in browser successfully but an exception will be output one or many times to the command line.

I am getting exactly the same issue, and I noticed that it also happens when running the cci org default command.

@yippie Thanks for reporting this. Python 3.13 made a change that now logs errors in file handling that were previously ignored. It’s related to how sarge (a library we use) interacts with io.TextIOWrapper.

This error doesn’t affect functionality. You can safely ignore it for now while we wait for an update from the sarge maintainers. If you prefer, you can downgrade to Python 3.12 to stop seeing the error.

@jstvz, thanks for clarifying! That’s great to know. I actually encountered an issue during my routine because the default org was set to an empty string (""). It seems like there might be an sf unset org somewhere. Thankfully, I was able to resolve it on my end.
