Expected to be able to filter for projects that did do not have cell counts. In order to find projects without cell counts, the filter was changed to [0].

    ],
    "selectedCellType": [
      "kidney cell"
    ],

There needs to be a distinction between:

{"cellCount": {"is":[null]}} # the project does not have cells
{"cellCount": {"is":[0]}} # the cellCount total for a project is 0
