title: Error Creating Folder in Sharepoint using Graph API
body: <p>I am attempting to create a child folder in Sharepoint and I am receiving errors. I can successfully create two levels of folders, but upon creating the third level, I receive the error below:</p>
  
  <p>"The request URI is not valid. The bound function binding to 'microsoft.graph.driveItem' does not support the escape function annotation."</p>
  
  <p>I am using Postman and taking the steps here to create folders:</p>
  
  <p><strong>1) Top Level: (Successful) - Folder1 Created</strong></p>
  
  <pre><code>https://graph.microsoft.com/v1.0/sites/&lt;SITE_ID&gt;/drive/root/children
  
  {
    "name": "Folder1",
    "folder": { },
    "@microsoft.graph.conflictBehavior": "replace"
  }
  </code></pre>
  
  <p><strong>2) First Child (Successful - Folder2 Created within Folder1)</strong></p>
  
  <pre><code>https://graph.microsoft.com/v1.0/sites/&lt;SITE_ID&gt;/drive/root:/Folder1:/children
  
  {
    "name": "Folder2",
    "folder": { },
    "@microsoft.graph.conflictBehavior": "replace"
  }
  </code></pre>
  
  <p><strong>3) Second Child (Fails)</strong></p>
  
  <pre><code>https://graph.microsoft.com/v1.0/sites/&lt;SITE_ID&gt;/drive/root:/Folder1:/Folder2:/children
  
  {
    "name": "Folder3",
    "folder": { },
    "@microsoft.graph.conflictBehavior": "replace"
  }
  </code></pre>
  
  <p>Any feedback how to properly create the Folder3 folder would be much appreciated.</p>
