Discriminant Analysis in Tidymodels


flexible_model <- 
  discrim_flexible( mode = "classification",
                    num_terms = tune(),
                    prod_degree = tune(),
                    prune_method = tune,
                    engine = "earth"
  )

set.seed(123)
flexible_wf <-
  workflow() %>%
  add_model(flexible_model) %>% 
  add_recipe(model_recipe)
flexible_wf



flexible_results <-
  flexible_wf %>% 
  tune_grid(resamples = heart_cv,
            metrics = metric_set(accuracy)
  )

error:

Fold01: preprocessor 1/1, model 1/10: Error: prune_method should be a single string value

What could be the reason for this?
