I met error when running CellChat "cellchat <- computeCommunProbPathway(cellchat)"

Question

[lujingyi]

First I read an RDS file Nhms<-readRDS("RT_cluster_id.rds") Then I create a CellChat object, Starting from a Seurat object using the original code cellChat <- createCellChat(object = Nhms, group.by = "ident", assay = "RNA") Everthing goes smoothly until cellchat <- computeCommunProbPathway(cellchat)

Thanks for your answering.
