title: ARM templates more lines
body: <p>I have an issue with ARM templates where, when there is an error, it will always say <strong>line 1</strong>.</p>
  <pre><code>##[error]Deployment template validation failed: 'The template resource at line '1' and column '3276'
  is not valid: The template function 'reference' is not expected at this location. Please see
  https://aka.ms/arm-template-expressions for usage details.. 
  </code></pre>
  <p>My ARM template clearly has more lines than 1. This makes troubleshooting very hard. How do I save the file so that is has more lines when an error occures??</p>
