How to use tidy_select_recipe() in a custom function for undoing target engineering

[awunderground]

I am trying to create a function to undo target engineering in a tidymodels workflow. I need to know which steps apply to the outcome variable to undo the transformations and I am trying to use the un-exported function eval_select_recipes(), which uses tidyselect::eval_select().

When I run this, I get an empty vectors:

library(tidyverse)
library(tidymodels)

data <- dplyr::select(mtcars, cyl, mpg, disp, hp)

mtcars_rec <- recipes::recipe(mpg ~ cyl + hp, data = data) %>%
  recipes::step_center(recipes::all_numeric(), -recipes::all_outcomes(), id = "centera") %>%
  recipes::step_scale(recipes::all_outcomes(), id = "scaleb")

eval_select_recipes(quos = mtcars_rec$steps[[1]]$terms,
                    data = data,
                    info = mtcars_rec$term_info)

# named character(0)

It works perfectly when I run prep(mtcars_rec) with the debugger, step inside the prep() function, and then run

eval_select_recipes(quos = mtcars_rec$steps[[1]]$terms,
                    data = data,
                    info = mtcars_rec$term_info)

# [1] "cyl" "hp"

In both cases, identical inputs are passed to eval_select() but one returns a length zero character and the other returns the correct named list.
