mutate_at() throwing an error with to_label() as its function in R

问题

I'm following this data cleaning instruction, but as of this line (also shown below), I get the following error: Error: Problem with mutate() input l5cathol.

Am I missing something?

library(tidyverse)
library(haven)
library(sjmisc)
library(googledrive)

googledrive::drive_download('https://drive.google.com/file/d/124WOY4iBXxv_9eBXsoHJVUzX98x2sxYy/view?usp=sharing','test.por',overwrite=T)
dta <- haven::read_por('test.por')

names(dta) <- tolower(names(dta))

# Convert variables of interest to character/numeric
vars_chrs <- c("childid","l5cathol","l5public","r5race","w3povrty","w3daded","w3momed","w3inccat","p5fstamp")

vars_nums <- c("w3momscr", "w3dadscr","p5numpla","p5hmage","p5hdage","c5r2mtsc")

dta <- dta %>%
  mutate_at(vars(one_of(vars_chrs)), funs(as.character(to_label(.)))) %>%  ##** @@ HERE throws error !!!
  mutate_at(vars(one_of(vars_nums)), funs(as.numeric(as.character(to_label(.)))))

With dplyr 1.0.0, using across, it is working

library(dplyr) # 1.0.0
library(sjmisc)
library(haven)
dta %>% 
   mutate(across(vars_chrs, ~ as.character(to_label(.))), 
   across(vars_nums, ~ as.numeric(as.character(to_label(.)))))
