After segmentation with cellpose, I ran Xenium Ranger 3.0.1.1
xeniumranger import-segmentation --id=my_ID \ --xenium-bundle=$DIR/outs \ --nuclei=$DIR/outs/mask_nuclei.ome_cp_masks.tif \ --cells=$DIR/outs/mask_cells.ome_cp_masks.tif

When I try to read the output folder with spatialdata_io (0.1.7.dev5+g82ff327), spatialdata (0.2.7.dev7+gd746485)
sdata = spatialdata_io.xenium(dir)
I get this error:
"ValueError: A linearring requires at least 4 coordinates."
