title: Get user profile (V2) in Microsoft Flow - How to use select query
body: <p>In Microsoft Flow, I'm trying to retrieve a custom field in a user profile. I'm using the "<strong>Get user profile (V2)</strong>" operation and I want to specify the custom field in the Query field.
  No matter how I construct the Query the operation returns this error: </p>
  
  <pre><code>{
    "error": {
      "code": "BadRequest",
      "message": "Query option '$select' was specified more than once, but it must be specified at most once.",
      "innerError": {
        "request-id": "785b1a00-e298-494f-95ad-af979856cbf4",
        "date": "2018-01-05T13:41:46"
      }
    }
  }
  </code></pre>
  
  <p>What syntax should I use to get, e.g. the field 'TestField'?</p>
  
  <p>I guess the value in the Query field is added to the OData Query created by the operation.</p>
  
  <p>Any help is greatly appreciated!</p>
  
  <p>Kind regards,
  Peter Rundqvist</p>
