This is a bug from vscode:

  1. Event onDidChangeActiveTextEditor be emitted with empty document when you open Settings editor.
  2. Then Event onDidChangeTextDocument be emitted even if you has not edited anything in setting document.
  3. So in this situation, onFileCoding function be invoked with global variable activeDocument is null. So get this exception: TypeError: Cannot set property 'lineCount' of null.
