TypeError: bbknn() got an unexpected keyword argument 'n_trees'

Hello,when I do sc.external.pp.bbknn(adata, batch_key='group'),it says
computing batch balanced neighbors

TypeError Traceback (most recent call last)

TypeError: bbknn() got an unexpected keyword argument ‘n_trees’
How to deal with it ?
