estimate-area returns with `too many values to unpack` error

Start with the estimate_area entry point in mapbox_tilesets/scripts/cli.py and calculate_tiles_area in mapbox_tilesets/utils.py, then reproduce the command using the reported NDGeoJSON Point geometry. Trace how the geometry reaches supermercado's burn function and verify that estimate-area completes and returns an area estimate for the supplied input.

I'm trying to get an estimate of the cost for the MTS publish process.

With the CLI and the estimate-area command, the program exists with an error.

the provided file is NDGeojson of about 2500 lines with a pretty long object, but with a very simple geometry part. eg:
