Problem with loading libraries in cloudml

[Z-ingdotnet]

I tried uploading my R training files from local project using cloudml_train, However, I encountered a lot of issues with uploaded jobs failing. I try to narrow down the issue by going back to the mnist example which run successfully and only modified the example slightly with adding a few libraries load as per below, retaining the rest of the code in the mnist example as they are library(keras) library(lime) library(rsample) library(recipes) library(yardstick) library(corrr) library(funModeling) library(tidyverse) library(readxl)

the error was similar to the other run of my own model. I am just wondering if this is something with cloudML package or the AI engine? It appears some dependencies were not accessible by cloudML engine. and unable to get from CRAN Please if anyone could shred some light that would be much appreciated
