Error while trying to create recipe

[beschlemper]

Hello,

I have a simple database with a column of dates and other columns with the variables. I had no problem with ARIMA or Prophet, but I got this error when trying to create the recipe:

`recipe <- recipe(value ~ Ano, training(splits)) %>%

• step_timeseries_signature(Ano) %>%
• step_fourier(Ano, period = 1, K = 3) %>%
• step_dummy(all_nominal())

recipe %>% prep() %>% juice()
A tibble: 198 × 50
Ano value Ano_index.num Ano_year Ano_year.iso Ano_half Ano_quarter Ano_month

The first rows of the database is just like this but it has 210 rows:

I already used the same script for other database, but with this one I keep getting this error.
