title: Information cannot be obtained from shared link URLs created by others
body: <p>I want to see the shared link information from the OneDrive shared link URL.
  If you use the shared link URL created by yourself (test001) as a parameter, you will succeed in getting the information.</p>
  <pre><code>string sharingUrl = &quot;https://test001-my.sharepoint.com/:t:/g/personal/test001_...&quot;;
  string base64Value = System.Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes(sharingUrl));
  string encodedUrl = &quot;u!&quot; + base64Value.TrimEnd('=').Replace('/', '_').Replace('+', '-');
  var item = await graphClient.Shares[encodedUrl].Request().GetAsync();
  </code></pre>
  <p>When trying to get information from a shared link URL created by another user (test002)</p>
  <pre><code>string sharingUrl = &quot;https://test001-my.sharepoint.com/:t:/g/personal/test002_...&quot;;
  string base64Value = System.Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes(sharingUrl));
  string encodedUrl = &quot;u!&quot; + base64Value.TrimEnd('=').Replace('/', '_').Replace('+', '-');
  var item = await graphClient.Shares[encodedUrl].Request().GetAsync();
  </code></pre>
  <p>System.NullReferenceException occurs in the above process.</p>
  <p>What am I doing wrong?</p>
