Error with add_continuous_stat function

[TomVillenet]

I've been experiencing difficulties for the past 2 days using the "add_continous_stat" function (which was working perfectly 6 months ago with the same code)

Here's the code from documentation for easier reproductability

library(dplyr)
set.seed(1123)
likert_lvls <- c("Never", "Sometimes", "Often", "Always")

df <- tibble::tibble( Q1 = sample(likert_lvls, size = 100, replace = TRUE), Q2 = sample(likert_lvls, size = 100, replace = TRUE) ) %>% mutate(across(c(Q1, Q2), ~factor(., levels = likert_lvls)))

tbl_likert_ex1 <- tbl_likert(df) %>% add_n() %>% add_continuous_stat(statistic = "{mean}") %>% add_continuous_stat(statistic = "{sd}")

And here's the error message :

Error in purrr::map():

ℹ In index: 1.
Caused by error in scope_tidy():
! The .$x data frame does not have the required "variable" column.
