title: Intellisense not working for remote VSCode window
body: <p>I am encountering this error where intellisense does not work for my python files in my ssh window (accessed with the remote development kit). I have uninstalled and reinstalled. My <code>settings.json</code> file on my remote workstation match my <code>settings.json</code> file on my laptop (where intellisense does work). I have tested to make sure that the correct python interpreter is selected on my ssh machine, and that this python interpreter launches and will run code.</p>
  <p>My output window previously showed this error:</p>
  <pre><code>Error 2021-04-30 13:53:16: Failed to check if file needs to be fixed [EntryNotFound (FileSystemError): Unable to read file 'vscode-remote://ssh-remote+172.16.214.73/home/jkang/.config/Code/User/settings.json' (Error: Unable to resolve non-existing file 'vscode-remote://ssh-remote+172.16.214.73/home/jkang/.config/Code/User/settings.json')

  }
  </code></pre>
  <p>I created this file <code>home/jkang/.config/Code/User/settings.json</code> with content <code>{}</code> in order to satisfy this error. It no longer shows.</p>
  <p>Additionally, when I googled this problem some suggested that I run <code>python: build workplace symbols</code>. However, I am not able to and I get the error</p>
  <pre><code>Command 'Python: Build Workspace Symbols' resulted in an error (command 'python.buildWorkspaceSymbols' not found)
  </code></pre>
  <p>Can anyone help me? This is very frustrating.</p>
