Error when running in M1 MAC

[RafaelOO]

What code produced the error?

library(forecast)
library(M4metalearning)
load("model_M4.rda")
tr <- window(AirPassengers, end=c(1959, 12))
forecast_meta_M4(model_M4, tr, h=12)

What error produced?

Error in if (class(newdata) != "xgb.DMatrix") newdata <- xgb.DMatrix(newdata,  : 
  the condition has length > 1

This error seems to come from line 184 of file https://github.com/pmontman/customxgboost/blob/master/R/xgb.Booster.R .

Environment?

MAC book Pro. M1
RStudio 2022.07.2 Build 576
xgboost compiled after executing devtools::install_github("pmontman/customxgboost"). To compile the code, I used Xcode command line tools 14. I installed this package by downloading it from https://download.developer.apple.com/Developer_Tools/Command_Line_Tools_for_Xcode_14.0_Release_Candidate/Command_Line_Tools_for_Xcode_14_Release_Candidate.dmg

Just adding, after following https://github.com/robjhyndman/M4metalearning/blob/master/docs/M4_reprod.md today, I see the same error at step > forec_result <- forecast_meta_M4(model_M4, x, h=h) in a very different environment (below). It may be useful to know that the error is not unique to the above Mac env.
