title: Azure DevOps release pipeline is getting failed when executing with publish profile service connection
body: <p>I am using the Azure DevOps release pipeline to deploy a web application built on top of Asp.Net Core to Azure app service. The app service is already up &amp; running.</p>
  <p>I created an azure resource manager connection with the publishing profile option through service connections.</p>
  <p>[ARM-Publish Profile Service Connection][1]</p>
  <p>Later I configured the release pipeline and used Azure app service deploy where I selected the publish profile connection.</p>
  <p>[Publish profile connection][2]</p>
  <p>As you can see in the screenshot, I was not able to select the already created app service name in the dropdown so I manually entered the app service name and saved the pipeline.</p>
  <p>Once the release pipeline got triggered after the CI pipeline, the task failed with exception <strong>credentials can not be null</strong>.</p>
  <p>Could someone please help me understand where I am making mistake ?
