NPE with latest darc when adding build to channel

• This issue is blocking NuGet’s insertion into .NET 5
• This issue is causing unreasonable pain

I’m trying to add a build to the channel .NET 5 Dev channel with the latest darc and I’m running into an NPE. darc add-build-to-channel --id 49099 --channel “.NET 5 Dev” --source-branch master Assigning build ‘49099’ to the following channel(s): .NET 5 Dev

Removing the blocking checkbox. Please let us know if the PAT addition works, and we’ll use this issue to track bubbling up the error in a more actionable way.

I was able to run the command, and https://devdiv.visualstudio.com/DevDiv/_build/results?buildId=3649872&view=results is running to publish the build to the channel, so I suspect some misconfiguration in darc, that we are not exposing correctly.
