Something Wrong with UMAP

[Laraine-Z]

Hello,
I am running bbknnR with code below:

data.merge <- data.merge %>% RunBBKNN(reduction = "pca",batch_key = "orig.ident",n_pcs=30,run_TSNE = F, run_UMAP = T)

It comes with the error log below:

Running BBKNN using RcppAnnoy...
Running UMAP...
Error in if (max(idx) > nrow(idx)) { :
missing value where TRUE/FALSE needed
Calls: %>% ... RunBBKNN.Seurat -> umap -> uwot -> check_graph_list -> check_graph
Execution halted

Could anyone help me to figure out the problem??

Thanks a lot!
