"unreachable" error when trying to load data with a dimension of all empty/null values

[mfulop]

When trying to load data with a dimension column with all empty string values, eg.

import Engine from '@chartshq/datamodel' // used version v3.0.0

async function f () {
  const DataModel = await Engine.onReady()
  const fd = await DataModel.loadData(
    [ { d1: '' } ], // d1: null also fails
    [ { name: 'd1', type: 'dimension' as any } ],
    {}
  )
  const dm = new DataModel(fd)
}

... an error is thrown on load:

    RuntimeError: unreachable
