“ValueError: No Voronoi neighbours found for site - try increasing cutoff”

Dear all,
Recently, I use matminer to featurize my dataset, but I met the error: “ValueError: No Voronoi neighbours found for site - try increasing cutof”. I had to increase the cutoff to so large, even about 50 angstroms, it still show this error, how should I fix this?
Thanks!
