  list(lm = lr_spec), case_weights = non_wts) %>% workflow_map("fit_resamples",
    resamples = vfold_cv(cars, v = 5))

Output
  [1] "Error in `fit()`:\n! `col` must select a classed case weights column, as determined by `hardhat::is_case_weights()`. For example, it could be a column created by `hardhat::frequency_weights()` or `hardhat::importance_weights()`."
