title: When I am running azure HTTP Trigger function i am getting 401 unauthorized
body: <p>I am trying to run Azure HTTP Trigger Azure Function and I am receiving a <code>401 Unauthorized</code>. It was working fine for me earlier.</p>
  
  <p>When I created the new function under the same Function App and copied the same code then also it is running fine but when I am trying to run my created function then I am getting the same error that I mentioned.</p>
  
  <p>I'm seeing the following logs in the streaming service.</p>
