How to solve my error in R Studio

Dear all, I am working on my university project which is about heating a house on one winter day. The assignment has an example with its instruction. In the instruction the temperature of house is 20 C, and I am supposed to change it to 19 C. i use "eplusr" as the EnergyPlus package and and " After working on the necessary steps when I want to simulate the model for 20C with the script:
model <- read_idf('20C.idf')
model
I get the following results in the console:

job <- model$run(NULL, wait = TRUE)

But when I want to simulate the model for 19C with the same script:
model <- read_idf('20C.idf')
mode
I got an error :
job <- model$run(NULL, wait = TRUE)
