The vapply error strikes again: values must be length 1, but FUN(X[[2]]) result is length 0 (Issue #1072)

Hello, I am running into an issue when trying to work with a list of Seurat objects, which I named seurats. not sure if this issue belongs to the seurat or seuratobject repo. Anyway, my code:
lapply(X = seurats, FUN = function(x){
FeatureScatter(x, feature1 = "percent.mt", feature2 = "nFeature_RNA") +
geom_density2d()
})

the answer:
Error in vapply(X = keyed.objects, FUN = function(x) { :
values must be length 1,
but FUN(X[[2]]) result is length 0

The versions:
packageVersion("SeuratObject")
[1] ‘4.0.4’

packageVersion("Seurat")
[1] ‘4.1.0’

R is 4.1.2
RStudio is 2022.02.0
OS is MacOS Monterey

If this is a bug that it's going to take some time to fix, what can I do in the meantime?
Many thanks!

Lili
