optimizeLSI for scRNA-seq gives Error in if (n < 0L) max(length(x) + n, 0L) else min(n, length(x)) :

Hi,
I've tried to run scRNA_01_Clustering_UMAP_v1.R using default parameters, and the
"scRNA-All-Hematopoiesis-MPAL-191120.rds" as input. When I do run the
#Optimize LSI Features
lsiObj <- optimizeLSI(assay(se),
resolution = resolution,
pcsUse = nPCs,
varFeatures = nTop)

it gives error after LSI 1 finished
Number of communities: 38
Elapsed time: 188 seconds
Additional LSI 2...
Error in if (n < 0L) max(length(x) + n, 0L) else min(n, length(x)) :
missing value where TRUE/FALSE needed

Anyone has faced with this error?
