Cannot read properties of undefined (reading 'getData')

[krishnagogada]

We got an error from the sentry as Cannot read properties of undefined (reading 'getData')

Here is the trace of the error

TypeError: Cannot read properties of undefined (reading 'getData')
  function popupSelectionChanged() {
                  closeAllTips() //remove(tooltip); //using close all , but its slower, comeback and remove single if its working right
                  var data = editor.completer.popup.getData(
                     editor.completer.popup.getRow()
                  )

We tried to reproduce the issue, but we didn't get the error.

This issue is reported in sentry when user clicks on div.ace_scroller > div.ace_content.

In which case editor.completer.popup will be null?
