title: Debugging of Jupyter notebooks in VsCode
body: <p>I'm using Visual Studio Code Insiders to work on Jupyter Notebook files. In the default version of VSCode it is possible to debug Jupyter notebook cells. Unfortunately, this is not the case with the insiders version.
  <a href="https://stackoverflow.com/questions/66412377/vscode-insider-jupyter-notebook-run-code-by-line/67966861#67966861">This post</a> describes the possibility to switch between the &quot;Native Notebook&quot; and the &quot;Jupyter Notebook&quot;.<br />
  In my case, adding the line &quot;jupyter.experiments.optOutFrom&quot;: [&quot;NativeNotebookEditor&quot;] to my settings.json file and reopen the editor leads to the following error message:</p>
  <blockquote>
  <p>Extension activation failed, run the 'Developer: Toggle Developer Tools' command for more information.</p>
  </blockquote>
  <p>I would be grateful if there is any idea what this error could be due to.</p>
