A NullReferenceException is occurring in a build of a project of mine when AppVeyor tries to upload the xunit test results:

https://ci.appveyor.com/project/martincostello/alexa-london-travel-...

This was causing the builds to fail until I changed the Powershell settings for my build script to ignore it.

AppVeyor should be correctly uploading the test results and not throwing an exception.

    This is also happening with a different project: https://ci.appveyor.com/project/martincostello/website/build/2.1.498

    Sorry for the delay in responding. We have been trying to determine the cause of this error but haven't finished investigating. We haven't forgot.
    The additional project should be helpful in the investigation, thanks for that.

    Can you try adding "parallelizeTestCollections": false to your xunit.runner.json file.
