title: VS Code - Request textDocument/definition failed
body: <p>I really like VS Code, which I use primarily for JS and React (jsx). Sometimes when I code, a panel pops up with a message:</p>
  
  <p><code>[Error - 13:45:45] Request textDocument/definition failed.
    Message: Request textDocument/definition failed with message: Cannot read property 'charCodeAt' of undefined
    Code: -32603</code></p>
  
  <p>How can get rid of this error message or prevent opening a panel when <code>Request textDocument/definition failed</code>?</p>
