Why is the code in the tidymodels.org tutorial not working?

Question

I am following the tutorial in the "Preprocess your data with recipes" section of the Get Started section of tidymodels.org.

When I come up to the following code, Cloud R waits for a bit, then times out of the session, not executing the code. Would anyone have an idea why that is?

Thanks.

flights_fit <- flights_wflow %>%  fit(data = train_data)
