AttributeError: 'NoneType' object has no attribute 'index' - Export CSV on filter box

[jerwen]

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 html page with an error message when clicking on the Export CSV button

Screenshots

How to reproduce the bug

1. Click on the Export CSV button of a filter box

2. See error

Environment

• docker image : apache/superset:1.0.1
• superset version: 1.0.1
• python version: 3.7
• node.js version: unknown

Checklist

• I have checked the superset logs for python stacktraces and included it here as text if there are any.

• I have reproduced the issue with at least the latest released version of superset.
• I have checked the issue tracker for the same issue and I haven't found one similar.

Could you provide some information on the use case for exporting a filter box to a CSV? There is a new Native Filters feature that will not use the filter box, and currently exporting a Native Filter to a CSV is not possible.

Thank you for your answer.
My point is that there are no known use case at this time for exporting a filter box to a CSV. Thus my request to simply discard the option in the dropdown menu for filter box, so we can avoid irritating error message for our users who often click on that button.
