polygonToCells The operation failed but a more specific error is not available

[h2923250018]

Hello, I do the Latest version of java, Due to the following polygon API in H3Core
public List polygonToCells(List points, List<List> holes, int res)
I use draws a circle (32-sided polygon) on the North Pole point,But the API returns no result and pops com.Uber.H3core.exceptions.H3Exception: The operation failed but a more specific error is not available。

The following video is a circle I drew through an online website https://geojson.io/. The circle that does not pass through the pole can be normally drawn through the last draw circle button on the right provided by it. However, as long as the circle passes through the pole, it will be deformed. I'm not sure if the geojson data it produces meets your requirements.

At the same time, I did not find a method to draw polygons in H3 API, so I implemented a method to draw a 64-deformed approximate circle with a radius of 500km and the center point being the North Pole. The visualization result is here https://geojson.io/. The site is not displayed, due to its possible deformation, not sure if it can be. However, it is possible to change the visual website to a non-GeoJSON format, the result is shown below,

and the data set,You can replace the relevant data of the coordinates node in geojson

if you find it troublesome to implement a round data set with errors, you can also have an equilateral triangle with the North Pole as the center point, and the data set points I tested will also find errors(Any figure passing through a pole)
