Additional Information

Anything helpful to shell into this or change the config manually may unblock me, willing to work on this issue too by digging into the source and perhaps handling this error but not sure how I could reproduce besides just trying to run this with a try/catch to skip this step if a failure occurs.

Note

If the bug report is incomplete or does not follow the provided instructions, it may not be addressed. Please ensure that you have followed the steps outlined in the README.md and troubleshooting.md documents, and provide all necessary information for us to reproduce and address the issue. Thank you!
