Clicking "Hide this column" on fips on https://covid-19.datasettes.com/covid/ny_times_us_counties shows this error:

https://covid-19.datasettes.com/covid/ny_times_us_counties?_nocol=fips

Invalid SQL

no such column: fips

The reason is that https://covid-19.datasettes.com/-/metadata sets up the following:

  "ny_times_us_counties": {
      "sort_desc": "date",
      "facets": [
          "state",
          "county",
          "fips"
      ],

It's setting fips as a default facet, which breaks if you attempt to remove the column using ?_nocol.
