Confusing error: rlang_cli_format_fallback

[JohnCoene]

The following (typo in column name) leads to a confusing error message.

cars |> 
  dplyr::mutate(
    new = purrr::map2(
      .data$speed,
      .data$dit, # wrong column name
      function(x, y) {
        x + y
      }
    )
  )

Error in `.rlang_cli_format_fallback()`:
! Bullet names must be one of "i", "x", "v", "*", "!", ">", or " ".
Run `rlang::last_error()` to see where the error occurred.

Thanks, I've reported the issue downstream: tidyverse/dplyr#6186

On the rlang side, we should improve this internal error and evaluate the error callback in the ns env rather than base to get cli formatting instead of the fallback.
