On an error message when using scales

[iagogv3]

I was using scale_x_date(labels=label_date("%d/%m/%Y")) for a data of class POSIXct so I got the error:

Error: Invalid input: date_trans works with objects of class Date only

Later I found the way to solve the error. The problem is that the message induces to think that the error is due to scales function label_date and not due to scale_x_date. I am not sure of this being the place to post this issue or the scales github or other place.

Minimal example:

last_month <- Sys.time() - 0:29
df <- data.frame(
  date = last_month,
  price = runif(30)
)
base <- ggplot(df, aes(date, price)) +
  geom_line()
base + scale_x_datetime(labels = label_date("%D")) # it works
base + scale_x_date(labels = label_date("%D")) # it does not work
Error: Invalid input: date_trans works with objects of class Date only

Thank you!
