spatialCluster() returns error "non-numeric argument to binary operator"

[ivykos]

I converted a Seurat object into a SingleCellExperiment object and then attempted to run spatialCluster() on the data with the following code

s1 <- Load10X_Spatial("Sample_V108-ILS19526ova-A", assay="Spatial")
s1 <- FindVariableFeatures(s1)
s1 <- ScaleData(s1)
s1 <- RunPCA(s1)
s1_sce <- as.SingleCellExperiment(s1)
colData(s1_sce) = cbind(colData(s1_sce), s1@images$slice1@coordinates) #add spatial info to SCE
s1_sce <- spatialPreprocess(s1_sce, platform = "Visium", skip.PCA = TRUE,
                            log.normalize = FALSE)
s1_sce <- spatialCluster(s1_sce, nrep=1000, burn.in = 100, q =10)

However, it returned the following error

Error in neighbor.positions$col + neighbor.positions$x.offset : 
  non-numeric argument to binary operator

Any idea what might be causing this?
