[GitHub] [superset] jerwen opened a new issue #14189: AttributeError: 'NoneType' object has no attribute 'index' - Export CSV on filter box

[GitBox]

jerwen opened a new issue #14189:
URL: https://github.com/apache/superset/issues/14189


   An error happens when trying to export a filter box to CSV.
   
   ### Expected results
   
   My opinion would be to discard the Export CSV button for filter BOX since, 
it has never worked and no one seems to have ever required it.
   
   ### Actual results
   
   An error message on a new tab when clicking on the Export CSV button
   
   #### Screenshots
