Error while reading the PBMC data.

[shnsk1995]

I am trying to reproduce the Integrating scRNAseq and scATACseq data tutorial using signac. However, when reading the data as below,

load both modalities

pbmc.rna <- LoadData("pbmcMultiome", "pbmc.rna")
pbmc.atac <- LoadData("pbmcMultiome", "pbmc.atac")

I receive the following error,

Validating object structure
Updating object slots
Ensuring keys are in the proper structure
Ensuring keys are in the proper structure
Ensuring feature names don't have underscores or pipes
Updating slots in ATAC
Validating object structure for ChromatinAssay 'ATAC'
Object representation is consistent with the most current Seurat version
Error in as.vector(x) : no method for coercing this S4 class to a vector

Can someone help me understand this error and how to overcome this error?
