Hi, you need to format code or logs here so that they're more readable for others.

You can find a Markdown code formatting guide here as well as some GitHub-specific information formatting code blocks here.

Thanks, Azure DevOps Migration Tools team

Hi there,
ACTION REQUIRED
This looks to be a complex issue that you will need to debug locally to figure out what is going on.
Debug in Visual Studio
Steps:

1. Fork this repository
2. Open this project in Visual Studio
3. Edit the Launch Profile to point to your config.
   
4. Craft a WIQL query to only load the work item with the issue.
5. Then set some break points and debug the issue.
6. Comment here with the results.

Your assistance is greatly appreciated!
Thanks, Azure DevOps Migration Tools team
