can anyone help me to fix this error message from the R’s nasapower library?

Error in post_process_plurals(pstr, values): Cannot pluralize without a quantity

# precipitation corrected sum (PRECTOTCORR_SUM)
library(nasapower)
clima <- get_power(community = "ag",
                   lonlat = c(47.68, 19.93),
                   pars = c("PRECTOTCORR_SUM"),
                   dates = c("2014-01-01", "2015-12-31"),
                   temporal_api = "daily")
clima
head(clima, 5)

Thanks in advance!
