Unable to detect CRS, GeoJSON has no "crs" property

I am getting this error

Error parsing Geometry Error: Unable to detect CRS, GeoJSON has no "crs" property.

with

GeoPackageAPI.open(file).then(geoPackage => {
  const table = geoPackage.getFeatureTables()[0]
  const featureDao = geoPackage.getFeatureDao(table)

  // colums which have statistical numbers to aggregate on the municipality
  const countableColumns = featureDao.columns.filter(c => c.startsWith('N_'))

  // statistical sum for all municipalities
  const sum = {}
  countableColumns.forEach(el => {
    sum[el] = 0
  })

  const geoPackageIterator = geoPackage.iterateGeoJSONFeatures(table)
  for (const feature of geoPackageIterator) { // <= ****** HERE *************
    for (const el in sum) {
      sum[el] += feature.properties[el]
    }
  }
})

I'm using the latest NPM version 4.2.3, and node v16.19.0

Any idea what the problem is?

@jfoclpf your file probably doesn't have a CRS set for the table you are querying. I recommend opening it in QGIS to confirm if it is not set and then set it.
