Problem Statement/Rationale

On Compass 1.40.4, when using a wrong date format on an aggregation step –  eg., ISODate("25-11-2019") –, while the pipeline displays data, when clicking "Export" the GUI becomes blank.

There is nothing indicating the problem with the date.

Steps to Reproduce

1st – Create a pipeline with a step like:
{
    $match: {
      $expr: {         $gt: [           "$statusChangedAt",           ISODate("25-11-2019"),         ],       },
    },
  }

2nd – Click the "Export" button.

Expected Results

To open the Export GUI page\window.

Actual Results

GUI becomes blank, but the top menu is visible and functional.
