Error: Problem with `mutate()` column `predicted`.
i `predicted = make_two_class_pred(...)`.
x replacement has length zero
Run `rlang::last_error()` to see where the error occurred.
In addition: Warning message:
Problem with `mutate()` column `predicted`.
i `predicted = make_two_class_pred(...)`.
i 'x' is NULL so the result will be NULL
