get_met_data() returns NAs and warnings regarding the column 'temp'

[hluling]

lga_met_data <- get_met_data( station_id = "725030-14732", years = 2017:2018 )
Returns 4 warning messages like this:
"1: Problem with mutate() column temp.
i temp = dplyr::case_when(temp == 9999 ~ NA_real_, TRUE ~ temp/10).
i One or more parsing issues, see problems() for details"

Then:
View(lga_met_data[1:10,])
It shows that the temp column just has NAs, inconsistent with the output shown in the example.
