title: How setup launch.json configurations for JavaScript Debugger (Nightly)
body: <p>I apologize if this question is very basic but I haven't been able to find a solution online. I am trying to set up my React application with the JavaScript Debugger (Nightly) extension in VSCode. However, I think I am not setting the &quot;url&quot; and &quot;webRoot&quot; properties correctly when trying to set up a launch request. The error message I get is &quot;Unable to attach to browser&quot;. Here is the last thing I tried:</p>
  <pre><code>{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.

      &quot;version&quot;: &quot;0.2.0&quot;,
      &quot;configurations&quot;: [
          {
              &quot;name&quot;: &quot;Debug Chrome&quot;,
              &quot;request&quot;: &quot;launch&quot;,
              &quot;type&quot;: &quot;pwa-chrome&quot;,
              &quot;url&quot;: &quot;http://localhost/HomePage&quot;,
              &quot;webRoot&quot;: &quot;${workspaceFolder}&quot;
          }
      ]
  }
  </code></pre>
  <p>I understand I might be missing something fundamental so I once again apologize. Something to consider is that I am running VSCode on VMWorkstation while running my React app on Windows 10 through Chrome. I am also aware I am using an outdated version of VSCode and that is because of CentOS 7 since the newest version of VSCode doesn't work on it. I know there is Chrome Debugger extension but I keep seeing that is is depreciated and that this JavaScript extension should be equivalent. I am wondering if one of the reasons I am having trouble is because I am using an older VSCode version, so maybe using the Chrome Debugger extension might work for me (assuming I have my launch.json correct)? Or could it be because I am using VSCode on a virtual machine, it is not able to find the browser url I am providing? I have tried downloading Chrome on the virtual machine too but no luck.</p>
  <p>I'd appreciate any noob tips to help me get started in the right direction. Using a debugger is something I have heard is very important and I want to get my head around this. Let me know if more information is needed to clarify the problem. Thank you in advance!</p>
