AttributeError: 'GeoSeries' object has no attribute 'coords'

The fix must be applied to the geometries themselves. I have added the relevant line to my post above.

Hi @DahnJ

Long time on this issue but..

I've modified polyfill with the idea suggested above (not sure if you were planning on making changes).

This solution below does two things:

1. If a given polygon is too small (returns no h3 cells), check iteratively with higher resolutions and return the parent cells at the res requested.
2. Add option for overfill returning also the outer edge cases using h3.k_ring.

I can submit a PR if you think this could be a useful change!
