title: Couldn't find a debug log in the cache or working directory
body: <p>I want to create a VSTS build with npm package auditing capabilities using npm audit. I added a few tasks to run npm audit. The command runs and I can see the details in the console/logs for all the packages. However, the task fails complaining about not finding a logs file. Any idea on how I can get the builds to stop working if I find a high vulnerability package? </p>

  <p><strong>EDIT</strong>
  This is the final line in the result when I run npm audit locally<a href="https://i.stack.imgur.com/oo4Yg.png" rel="noreferrer"><img src="https://i.stack.imgur.com/oo4Yg.png" alt="enter image description here"></a>
  Notice how it displays vulnerabilities in categories. I want the build to not proceed if there is a non-zero value for High vulnerability. </p>
