What happened?

I was trying to migrate the build pipelines and have been receiving the error saying value can't be null and parameter name seems to be source. Please let me know if I'm missing in the config

Debug in Visual Studio

Same config file is working when I try to migrate individual build pipelines but throwing this error when try to migrate all

Hey, not sure if you sorted this out, but I was getting the same error and it turned out it was because I was attempting to migrate a build that had a non-standard build step that wasn't available in the Target project.

In my case, it was specifically a SonarQube code analysis step that caused the problem, but I'm assuming any build step that is not available in the Target project will cause this error.
