xreg parameter hts R package ARIMA

Question

I am trying to add an external regressor xreg into the hts package, however I am getting an error regarding the number of rows (140) despite my external variable has the same number. I have checked other answers but mine is more simple:

Here is the reproducible example

library(hts)
abc <- matrix(sample(1:100, 32*140, replace=TRUE), ncol=32)
colnames(abc) <- c(
  paste0("A0",1:5), 
  paste0("B0",1:9),"B10",
  paste0("C0",1:8),
  paste0("D0",1:5),
  paste0("E0",1:4)
)
abc <- ts(abc, start=2019, frequency=365.25/7)
x <- hts(abc, characters = c(1,2))

data <- window(x, start = 2019.000, end = 2021.166)
test <- window(x, start = 2021.185)

x2 <- runif(n = 140, min = 1, max = 10) #External regressor with the same size

fcastsxreg <- forecast( data, h = 2, method = "comb", algorithms = "lu",  fmethod = "arima", weights=, "wls", nonnegative=TRUE, xreg=x2)
accuracy(fcastsxreg, test, levels = 1)

The error message is about the mismatch between de size of abc matrix an x2 vector despite both have 140 rows

Error in model.frame.default(formula = x ~ xregg, drop.unused.levels = TRUE) : 
  variable lengths differ (found for 'xregg')
In addition: Warning message:
In !is.na(x) & !is.na(rowSums(xregg)) :
  longer object length is not a multiple of shorter object length

Thank you
