Bias correction on seasonal forecast produces error with example dataset

[durutti]

I am having an issue on using the window option when bias correcting seasonal forecast. So I went back to the examples to figure out
what I am doing wrong.
However
require(climate4R.datasets)

data("EOBS_Iberia_pr")
data("CFS_Iberia_pr")
y <- EOBS_Iberia_pr
x <- CFS_Iberia_pr
eqm.join <- biasCorrection(y = y, x = x,
precipitation = TRUE,
method = "eqm",
window = NULL,
wet.threshold = 0.1,
join.members = TRUE)

The above code produces the following error

[
Error in if (dft == 1) { : missing value where TRUE/FALSE needed
In addition: Warning message:
In setGridDates.asPOSIXlt(grid) :
[2021-11-28 09:37:31] Time zone unknown. It was set to the current auto-detected time zone (EET)

Than you very much in advance
