circos.heatmap(): Error in rowMeans(m) : 'x' must be an array of at least two dimensions

I'm following the tutorial to make circular plots in R. Suppose I have this dataset:

set.seed(123)
    mat1 = rbind(cbind(matrix(rnorm(50*5, mean = 1), nr = 50), 
                   matrix(rnorm(50*5, mean = -1), nr = 50)),
                cbind(matrix(rnorm(50*5, mean = -1), nr = 50), 
                   matrix(rnorm(50*5, mean = 1), nr = 50))
                )
    rownames(mat1) = paste0("R", 1:100)
    colnames(mat1) = paste0("C", 1:10)
    mat1 = mat1[sample(100, 100), ] # randomly permute rows
    split = sample(letters[1:5], 100, replace = TRUE)
    split = factor(split, levels = letters[1:5])

I tried using Heatmap and it returns appropriately.

library(ComplexHeatmap)
Heatmap(mat1, row_split = split)

enter image description here

However, when I try to use circos.heatmap(), it returns error:

library(circlize)
col_fun1 = colorRamp2(c(-2, 0, 2), c("blue", "white", "red"))
circos.heatmap(mat = mat1, split = split, col = col_fun1)
circos.heatmap(mat = mat1, col = col_fun1)
> Error in rowMeans(m) : 'x' must be an array of at least two dimensions

The matrix itself has a dimension of 100 x 10. Is there anything I'm missing?

Had the same issue with CRAN version, but it was rectified after installing the dev version

devtools::install_github("jokergoo/circlize")
